Corsair H80 vs Antec H2O 920 CPU Coolers @ HH

Corsair H80 vs Antec H2O 920 CPU Coolers

Today we have the latest and greatest from Corsair and Antec connected to our test system as we put the H80 and Kuhler 920 head to head in order to find out which is best. Can Corsair (and CoolIT's) latest design beat the critically acclaimed Asetek/Antec model?

Re: Corsair H80 vs Antec H2O 920 CPU Coolers @ HH

Exactly the review I (and half of the internet) was looking for!

Was the slight ticking noise coming from the fan or from the pumps? It was more noticeable on the 920 then on the H80, on the low speed recordings. At high speeds the sheer scream of the fans seem to be drowning it.

Because I was dumb enough to buy a nice chunk of Kingston's HyperX T1 Black memory, I am looking to buy one of these sealed units (the 620 and H60 are also in the running) but there are a lot of reports on the web about units with problems like air bubbles stuck in the pumps and very disturbing pump noises as a result. Also some of the units (from both manufacturers) seem to not have enough coolant.

Any similar problems with any of the review units?

Re: Corsair H80 vs Antec H2O 920 CPU Coolers @ HH

How is the performance of this compared to the H60 and H70? Would you recommend the H80 or the 920 above those?

Re: Corsair H80 vs Antec H2O 920 CPU Coolers @ HH

The 920 was the performance leader in a market that included the H60/70 so yes, the H80 is a step up again. In terms of what you should buy, the 920/H80 are both great purchases and I would base the decision on which software suite you think is best... or maybe even if you care about software at all (in which case the Corsair might be the way to go as it is essentially software free now and optional later).

Re the question on noise and bubbles, both seem fine. Those vids were taken near the beginning of the testing so have improved over time. Essentially silent now.

So it's just a question of a small "burn-in" period of a couple of days.

Thanks!

Re: Corsair H80 vs Antec H2O 920 CPU Coolers @ HH

I've heard complaints about the H80's relatively cheap/shoddy construction. A major one is that the faceplate on the H80 is held on with relatively cheap tape and the fan controller has issues with cheap materials (people receiving it bent, faceplate missing, frayed wires, etc). Any input on this?

Re: Corsair H80 vs Antec H2O 920 CPU Coolers @ HH

I've tried getting a fingernail under the faceplate and couldnt, its on there very strongly. For the fan controller the button feels fine, the wire that comes out of it ends in a normal molex and 3pin power connector, its just standard wiring that I cant see any issues with... comparible quality to the 920 on the wire front.

Re: Corsair H80 vs Antec H2O 920 CPU Coolers @ HH

i got the 920 bout 2 wekks ago..

this review is pretty much spot on. i went the 920 over the h70 mainly because of software and the IMO better tubbing. (had herd other reviews say the corsair h70 wasnt as flexable)

i have the fans sucking air from outside the case, using the stock thermal paste that came with the cooler. i have an i5 2400 3.1 and the cpu temp at idle is 21-22deg celc after bout 30mins in real temp. (dont know if this helps lol)

i have the radiator mounted so the pipes are coming out of the top not the bottom in regards to how i postioned it. IMO the pipes are less tangled and look alot neater when looking at the case through the window. (i have a black corsair graphite 600t case)

when i first turned it on i could hear bubbles but after about 5 mins they went away and i havnt herd them since. also the ticking noise that sounds like a fan cable hitting the fan in the video i had also. took me ages trying to figure out what it was to no avail. just tapped the radiator a few times and it seemed to go for bout 10 sec then come back. when the fan rpm is increased the noise goes away. since playing silly buggers with fan speeds the ticking noise has since gone away. at a quess this happend bout an hour into playing around with it. so no noise at all anymore.

seroiusly i can hear the fans going full pelt while im standing down the other end of a hallway in my house.. (WTF is that noise lol)

also temps in the software are not cpu temps but rather coolant temp. had to manually set fan speed changes based on water temp vs. cpu temp in real temp.

all out im happy with what i got and for the price a paid.

anyways hope this helps someone

Re: Corsair H80 vs Antec H2O 920 CPU Coolers @ HH

After reading the review a third time I decided to place an order for an H80, should be arriving at my door on Friday. A bit expensive for my taste, but I hope it will allow me to return my i7 930 to it's "default" 4GHz (200x20) overclock, the Xigmatek Gaia just can't do that on these hot summer days.

Re: Corsair H80 vs Antec H2O 920 CPU Coolers @ HH

Question to Stu/Craig/Others: The H100 is going to be an extra long rad. In normal cases, where will this go (assuming normal = fulltower enthusiast case)?

And yeah, my 980X gets up to right arond 68C at 4.2ghz with the H50...I'd be hoping getting an H80 or H100 would either let me crank it up to 4.4ish or get it under 65C (I'm using 1900RPM 110CFM fans in intake push/pull) (still debating getting one).

I'd assume you'd have to mount it at the top of the case, this is my Lian-Li P80



So that's where I'd have to stick it, wouldn't fit in the rear, I can't think of any cases off the top of my head that have dual fans at the rear big enough.

Maybe Stu will have a better idea

EDIT: I'm fairly sure the Corsair 700D I had had the same configuration at the top, infact it had space for 3 fans, same will go for the 800D.

Re: Corsair H80 vs Antec H2O 920 CPU Coolers @ HH

So my H80 arrived... With my i7 930 @stock I'm getting 57C-60C at idle with the fans on low, 55 with the fans at medium and 50-ish with the fans at high. Pump is @2000-2150 RPM.

There are no strange noises coming from it, there is a slight high frequency but inaudible vibration, and the sound of an occasional air bubble. The result is my case gets incredibly HOT and every other component close to the top side of the case warms up considerably as a result. This includes the chipset (64C) and the memory (47C). I shook the radiator a bit, and there seems that there isn't enough coolant in there, as it's making this "watery" noise, like when you shake a half full bottle of scotch, but I'm no expert on what the adequate coolant level should be. But water seems to be circulating, since the tubes get hot also.

I tried Prime95, but the temps quickly rose to above 80 so I stopped it immediately. I rechecked every nut and bolt, they are all secure, there is contact where contact is needed.

Any advice?

Sihastru, Corsair say it sounds like a faulty unit (bad luck i guess). Check your PM's and I will put you in touch with them direct to get this resolved asap.

Re: Corsair H80 vs Antec H2O 920 CPU Coolers @ HH

Thank you Veridian3 for the info, a friend of mine should get a H80 at the beginning of next week and since I am the one that maintains his system (no, I didn't influenced his purchase, he wants one, even if he knows what happened to mine and I advised him against it) he agreed to let me try it first on my system, I have the Gigabyte X58A-UD7, and I want to make sure there isn't any hidden incompatibility issue.

I studied the board and the installation pretty well and haven't seen any problems, contact with the CPU looks fine, the pump assembly just barely clears the capacitors around the socket (even if they are very close).

If his unit works fine, then I will take a few pictures, comparative screen shots, maybe add a small clip, then I will send them to my online retailer as proof of a defective unit and hopefully they will exchange it. It is difficult to ask for warranty services on such items, when the defect is not immediately apparent since performance issues aren't covered by the standard warranty, only obvious hardware defects.

I they won't help me, then I will try to get in touch with Corsair directly.

Thanks again.

Re: Corsair H80 vs Antec H2O 920 CPU Coolers @ HH

I hope your issue gets solved, it really seems odd, and if it wasn't a deffective product, I would think twice, if not three times before buying the H80 or the H100 for that matter.


Now I know that for warranty issues, I better get items from a local retailer, it might make things easier, and if the vendor is a jack@$$ I can get my hands on him if necessary

Re: Corsair H80 vs Antec H2O 920 CPU Coolers @ HH

Update, if anyone is interested.

My friend's H80 arrived and I'm trying it out in my system and it actually works very well. Because the bundled fans are quite loud, I experimented a bit with two Noctua NF-P12 fans @1300 rpm, they seem to produce more airflow at full speed (~54CFM) then the Corsair fans on low, while being actually quieter. Almost as much airflow as the Corsair fans on medium, but not quite.

At full speed the Corsair fans do push a LOT of air, they also sound like an old industrial vacuum cleaner, as you can see from the review, so it was expected, not a complaint, it just seems like a lost opportunity on Corsair's part, water cooling should as quiet as possible.

Also it seems that the 3 speed levels available on the unit will not work with fans that are so slow @1300rpm, it doesn't matter which level is selected on the unit, the Noctua fans seem to be working at their full 1300rpm all the time. I didn't expect this, I hoped that the unit would self regulate itself and create three speed gradients with any fan, but that doesn't happen. Perhaps on the low setting there is a variation, but it's too small for me to observe.

A good fan option for this unit should be the GT 1850rpm fans, and those should have usable low/medium speed levels up to 1300/1600rpm, and then an extra 250rpm for the full speed. I'm just speculating at this point, but if it's not then I would consider it to be another missed opportunity.

I shook this new radiator too, and it seems just as full (or I should say empty) as mine does. Maybe mine is missing enough coolant to not function correctly.

With higher room temp then when I tested mine (at lest 6C higher) and with the Noctua fans my i7 930 is @38-46C (core probes have quite a gap) at idle and under 70C during Prime95 (blend mode). As it is summer I consider these to be acceptable. With the Corsair fans @medium/high the temps are lower, but the noise is just too much for me.

It can also handle my desired 4GHz OC (200x20, 1.26V, HT on, Turbo off, all six DIMMs populated), idle temps are just a hair higher then stock, and Prime95 load is at ~82C (maybe +4C more if I let it run more then 15min). Seems high, but with quiet Noctua fans, I think it's kinda great.

This is spot on what I was hoping to achieve with mine, hopefully a replacement for it will do at least as well.

I took screenies with this good unit (too bad it's not mine) and tomorrow morning I will pop in my broken unit and take a few snapshots with it's temps, and it's going back by courier to the (online) store.

So yeah, bad luck for me, no compatibility issues, just a malfunctioning unit, even though I don't know the exact cause.

Good to hear, kind of... be sure to speak direct to Corsair if you run into any issues with the return.

You dont say what cooler you use but regardless, the results in the review are accurate and correct.

I suggest you either change your cooler to an alternate model if you want better performance or maybe try and re-install yours as it may not be making a good contact with the CPU... or maybe your thermal readings are off.

Re: Corsair H80 vs Antec H2O 920 CPU Coolers @ HH

Thread resurrection for good news and not so good news update.

Got a replacement H80 unit this morning, installed it and it works fine. It took quite some time, but what can one do... Just to show I hold no grudges against Corsair I picked up an AX850 too (it seems I was on an unlucky streak as my lovely Ultra X4 850 that I won here some time ago gave up the ghost).

Looking forward to a GPU upgrade, I'm trying to figure out if it's a good idea to wait 6 months for 28nm or just go 580 2xSLI right now. This is where the AX850 comes in. But that is another story.

Re: Corsair H80 vs Antec H2O 920 CPU Coolers @ HH

Hi all, new to this forum. Having just installed my new mobo, CPU and RAM a week and a half ago I am still using the stock cooler and I've been closely looking at these coolers.
One thing which nobody seems to have mentioned is that on the Corsair the pipes seem to emerge on the right side? If I am right, on my mobo this means they would possibly be a tight fit against my RAM or not fit at all.
However on the Antec 920 the pipes seem to come out of the bottom and the worst they could do is block the "Republic Of Gamers" LED logo.For this reason I'll be getting the 920.
Another thing is that my back exhaust fan is a 120mm LED. I'm hoping I may be able to sawp the 920's inner fan for this - certainly I have seen one video on YouTube where he appears to have done this. Has anyone else done the same?

HI, the H80 wont block your memory slots, it stays within the Intel heatsink location area. As for the fans, you can use pretty much any standard size fan with these coolers.

Re: Corsair H80 vs Antec H2O 920 CPU Coolers @ HH

Most people mount the cooler the way it's shown in the manual, but you don't have to.

In the case of the new Corsair coolers (actually made by CoolIT, and based on their ECO line) the pipes/tubing are really rigid, making it kinda difficult to mount, and as such mounting it so the pipes come out the right side (when the rad is on the back of the case) is just easier.

With the Antec cooler people usually mount it so the Antec lettering is horizontal making it easy to read, but again, you don't have to. The pipes are less rigid; they are soft rubber tubing, and bend easier, so you could pretty much mount them on any side you want. Just don't bend them so much that they fold or crease as that will effect circulation of the liquid inside.

BTW, if you do buy the Antec cooler don't rely on the manual. It's useless (as is the PDF on the CD). Instead, use it (loosely) in conjunction with THIS reviewers installation.

Thanks for the replies.

"With the Antec cooler people usually mount it so the Antec lettering is horizontal making it easy to read, but again, you don't have to."

I was conscious of this but I am looking at the aesthetics of my system as well as the functionality and the trouble was that it would prey on my mind even if nobody else noticed. Like when I was 20 and put some of my bedroom wallpaper on upside down.Too late my niece pointed it out when it had dried.
