This looks like the way to go. Direct air cooling from out side of case to the CPU.

mmm..looks a little prehistoric to me Any info about achieved temps?

[MIG-31]

seen around in a few stores,can't see that being very successful.

[TonyMonTana]

The idea is nice but it looks horrible, reminds me of a tumble dryer with the exhaust poking out of it!
It also seems that all it will do is take the heat from the cpu out of the case which if you have good airflow and fans postioned correctly aint a problem anyway.

[The_Neon_Cowboy]

it a duct mosd its been around for a while... big deal woul be lots and lots of dust...... there not the best idea



i dont take those temps eather unless the hot one is from a fanless case

[jjmd]

You think, you can allways put a filter on the front. I thought it would be nice ideal with a valcano fan84 cfms on the front blowing in, and another volcano fan on the heatsink blowing in for a push pull setup.
Then it would be a dedicated air sorce to the CPU. The nice thing about a case fan on the side case would mean it would be right there. Very short distance to the heatsink. Or even right out the back.

EDIT LOOK at the picture on their site it allready comes with a filter.




If i can find it for sale somewere cheap i might just try it.

[Oblivious]

Two words: Open Case. (open case works)

[wertret]

I have this installed on my thermaltake volcano 11+ xe. It works and looks great.

[jjmd]

Has anybody seen one for sale and how much it is. I would like to try it and cant find were they are sold.

Thanks

Oblivious, if opencase cooling works best for you then you must of had verybad cooling to start with to feel the need to open your case.
A case with good airflow and correct fan placment will always beat opencase, and think of all that dust getting in your case, also when your ambient temp gets high (in winter with heating on) your comp will still get very hot.
Spend 30pound on fans and close your case, think of the years your knocking of your rig.

[jjmd]

Your case is open to the elemants anyways if you run fans. All this dose is deticate the air to the heatsink.

I really have no cooling problems, just looking for better way of cooling, Beside going water cooled!

By the way Tony look @ my sig, i have 8 Volcano @ 84 cfms each Nowthats cooling 672 CFMS total. May sound like a plane but what the heck

[Logla]

I have a coolermaster heatpipe HSF on my P4. i've been getting some low low temps just on air so tried a thermal probe under the CPU this weekend. I am astounded by the thermal performance - put it this way, the machine idles at 21 degrees celcius and gets to about 35 under full load. These readings are at a failed attempt at lapping the base so If I can get that done properly then I should see sub 20 degrees.

[Al_Vampyre]

I saw a review of this somewhere and they weren't too impressed...I'll see if I can dig it up!

[jjmd]

heres a place that sales it only 29 bucks.

http://www.pccasegear.com/prod1006.htm

or even better 18.95

http://www.casecooler.com/suovairdu.html

or 15.95

http://www.jab-tech.com/catalog/prod...kit__Blue.html

Well for 16 bucks it might be worth tring

[jjmd]

Hey al try and find the review that would help alot. Thanks

The easy was to great cooling!

No way man! In my experience:

Fans can only approach what open case in terms of performance. Put it this way: in a closed case environment you have room air and case air. The case air heats up because of heat produced by your pc. The fans you install in your case try to mix the case air and the cooler room air in an attempt to lower the temperature inside your case to room air temperature. But the process is not perfect so the air temperature inside the case will always higher then the room air temperature.

When you run a computer open-case there is only one body of air (There is nothing impeding the free flow of air to and from your computer components). The "case" air temperature is equal to the room air temperature. Open-case beats fans in performance - no contest.

Dust? Well whtas the difference between a fan cooled and an open case computer? There is none- both of these setups circulate dirty air around parts and the dust settles on the parts. Thats that. That is unless you add filters to your fan cooled system. But look for some pics around these forums and tell me how many fan filters can you spot?

As for ambient temperature, hoo-boy. It's not like fans magically cool the air going into your PC. An open case PC and a fan cooled PC will both be adversely affected by rising ambient temps. But the same argument applies: an open case PC's "case" temp will be at ambient while a fan cooled PC's temps will be higher than ambient. Open case is still the winner here.

So whats the deal?

In terms of dust - compare a pair of 1 year old computers, an open-case and a fan cooled, in terms of the amount of dust that has collected. I can't tell the difference. Can you?

This is pretty silly IMO when you first put effort into sealing an environment and then again put effort into unsealing it. When you run a computer open case there is only one body of air and as a result you get improved cooling performance. So why do we need cases anyway? To protect against coffee spills? No thanks I'll pass....

I'll keep my 30quid and I will enjoy sitting next to my fast, quiet, clean, long lasting, open case computer.

P.S. - For the record I switched to open case from 2 Delta 80mm 85CFM fans working as case fans.
P.P.S - This reply has been influenced by rage. Thank you for insulting my computer hardware and my computer skills.

[studbagel9]

I am running with one 120 mm, and 6 80 mm fans in my computer. It's not the quietest thing in the world, but my cpu never goes above 35*c under load, and idle my sys temp is the room temp, about 23* c

[jjmd]

The posts u get from just one question "LOL"

[Judas]

i have an ambient room temp of around 19*C right now... opening my case....... actually puts my temps up another 5*C... (OCed Barton 2500+ ).......

Thats all very well but you seem to have forgotten the effect that the air (ie fanned in and fanned out) being in movement has as that adds to the cooling ability of the air...if it didn't we'ed all just be using passive heatsinks and no fans!

[Judas]

run a car without a fan for a bit........ a a small very easily heated body of air.... moving with a current..... will produce better results then a large body that has some very small changes in drift.... will not produce much of any good results...... When you heat something up...the majority of the air around it only gets hotter.... moving it is the key..... If your computer doesn't have a neat...or doesn't produce heat like some of ours do.. then none of what i or anyone else says.... means anything...

Yea, I can see the dust on there now.. look at the IDE cable.. it is brown.... Same around the CPU....

The problem I have with your statement is that you assume that fanning in air into a case at high speed through a small hole produces more airflow (CFM) than letting air circulate freely through a huge hole. I'll leave it up to you to prove that statement.

But if you ask me the situation looks rather dark: your fan has a cross-sectional area of (4"x4")= 16, the gaping hole in the side of my computer has a cross sectional area of (2'x3') = (24"x36") = 864 square inches. Thats 216 times larger. If I have a 1mph draft around my case... then your fan will have to blow air at 216mph in order to move the same volume of air. (And god help you if I fart into the case, your fan will have to blow air at hypersonic speeds! :P ). So let me assure you that airflow with an open case computer is very respectable - you shouldn't just dismiss it as negligible. On a side note I don't expect my comp to be cooler than yours if yours is hovering off the table or is built like a wind tunnel.

The deal is this: I hate it when people knock open case cooling. It's effective, it's quiet, it's cheap and it is way better than "just good enough". If you wanna fan cool your case then go ahead because that is the standard way to do it. In the meantime I have my own, and IMO reliable, experience telling me that open case cooling is just great. And like the anal-retentive bastard that I am, I intend to show up at random times and just remind people that open case kicks ass.

Have a nice day.

P.S. - Look up Zalman and you will be pleasantly surprised re: passively cooled CPUs.
P.P.S. - A fact of little consequence: LN2 overclockers, who are as a group are probably leading the world in terms of overclocking/performance, use open case cooling : Link goes to one example.

I dont know about you, but I have alot of brown IDE cables. Almost all of mine are. Even when I just bought them.

Theres no way dust could be around the CPU, I just got this mobo, and this was taken before ANYTHING was fired up!

[Necrosis]

Actually this idea would be great for one heatsink in particular..the Alpha's! I had this idea with my P4 setup but never did get around to setting it up.

[jjmd]

What i understand about it. Is if your cooling your cpu with case air its all ready mixed with warm air, Right. So if you have a devise like this that is the same size as the fan blowing in cold air at say 84 cfms from a volcano fan and another on the heatsink, thats direct cold air from out side the case with no restictions. so thats has to be better. As you will have great flow and freash air . Thats what the heatsink is doing anyways blowing warm case air cross the cpu die then pushing that warm air back through out the case. So how you can argue about freash air blowing across the cpu is what i dont understand.

If the devise is placed on the back of the case to the heatsink u have like 5 inches of travel, wont be any restriction there. take a look for your self its self explanitory.
