SO, nothing really of interest perhaps here.... nothing involving overclocking or whatnot.

Just a machine i had come in that someone assembled and left my jaw hanging for awhile on how it was assembed and why?


Anyways, it's one of the early Prescott cpu's, so they run bloody damn hot.

Heres the dilema..


The machine was in need of a serious upgrade in the ram department.. however the damn "non-stock" heatsink that was put in the bugger has a off center square 80mm fan on it, which wouldn't have been a problem, however the little metal bars that stick out of the heatsinks outer edges pretty much make contact with the ram thats already installed.

So essentially, every time you want to replace the memory or do anything reguarding the ram installed, you'd PHYSICALLY have to remove the heatsink. Stupid? I think so.

The heatsink is something i've seen before, while containing a copper core, it didn't perform all that great imo, kept the idle temps just below 50*C mind you, but still.

So, in a hunt to find something relatively cheap, i was hoping to find the Q6600 heatsink i hadn't used... apparently i used it, as it would have done a damn decent job as it contained a far better cooler then this pos, plus would grant access to the ram at will.

But alas nothing, however i did find a stock E5200 cooler. Obviously not going to do the job, but i figured wtf, i'll give it a whirl and see what happens.

Idle, the sucker got to over 55*C and kept climbing, i didn't feel like taking a chance and powered down.

Today i received a Freezer 7 pro. Cheapest heatshink i could get that had a copper contact and wouldn't butt it's ass into the ram. (the socket and ram modules are extremely close to each other.)

Cleaned up the cpu, cleaned off the thermal paste that came on the freezer 7 pro, Slapped some OCZ Freeze thermal paste on the cpu and plugged it all in.

Fired it up, Rock solid idleing at 32*C now.

I'm still quite happy with the results of anything i've put a freezer 7 pro on.

indeed. It's a great little cooler!

But what I experienced was that its ass can be in the way of the northbridge heatsink. With my particular setup I had to rotate the acrtic freezer to blow the air out of the top of the case instead out of the rear.

yeah it's a relatively low sitting cpu...

heh.. guess what...

not only did i get lower temperatures.. but i've got the bugger running 3.1ghz now with zero temperature change worth mentioning..

apparently this is an excellent model. Just unfortunate that the board it's sitting on gives only FSB increase values, no voltage or any other values you can change.



still an excellent upgrade... will post @ 160/165mhz (165mhz fsb is max available on the board though) but won't load windows let alone read the cd=rom or anything. i haven't tried anything between 156-159mhz though.... not bothering... my memory is @ 194mhz instead of 200

31C with the new cooler on a prescott? i call BS. lol. why do i say this? because i myself also have a prescott CPU.

however, i have the best HSF combo anybody could ever have for the s478. a ThermalRight sp-94 and a 92mm Vantec Tornado.

even with that set up, my idle never goes down below 48C and under load it'll cap off at 55C running stock. back when i was heavy into OCing my rig, at a 4.16Ghz clock speed (1,040Mhz FSB, 520Mhz DDR from stock 400Mhz (1:1 ratio) @ 2.5-3-3-7, 2.8v) which was bench stable. at that point, idle was ~55C and load was ~65C.

also, back when i used to work at the store and we were building/selling prescott based systems, i continuously saw an average idle temp of between 48C to 53C.

so, again, i call BS on a new idle temp of 32C after this cooler was installed.

i've still got my sisters camera.... i'll fire it up.. use windows xp for awhile doing various tasks.... i mean all i have to do is pop it on Driverheaven with the BFG add and the cpu still peaks out at 100%... i'll leave it there.. (maybe i'll get lucky and get 2 bfg ads again)

Then i'll take a picture.

Everest mostly agrees, as it registered at first 29*C, and then 34*C so it seems to jump around there.

No sensor is perfect, but even trying to touch the copper heatpipes near the base, it feels actually just warm to the touch...

Plus apparently this specific 505 revision (one of the newest ones i beleive) is notorious for running cooler, better overclocking potential.. and the like.

Hopefully i remember the camera tomorrow morning...

see ya

Heres Idle temps..

i let it sit at the bios hardware monitor screen for over 30 minutes and then snapped this picture.... 34*C (2*C difference meh)

And then i snapped a picture after sitting in windows xp for 15 minutes. Spot on

(last picture is of the case (hunk of crap imo) and the parts.)

BTW, this is while overclocked to 3.1ghz

i call faulty temp sensor .

but, you said 505 p4? the 5xx series p4s were the initial switch to the s775. there was no difference between the 5xx p4s which had the s775 configuration vs. the s478 p4s aside from the physical configuration of the LGA to PGA pin layout of the two CPUs.

if that's the case, and you have a 5xx p4 and not a s478 p4, then i *could* still see that being the case. but otherwise, i call a faulty sensor.

oh, and i forgot to mention earlier that my p4 is also lapped

Freezer 7 Pro only supports LGA775 socket so it must be CD's.

I do have a 478 socket Cele idling @36C with Vcore set to 1.65V on a Katana2 though

yea. it is. on my initial post in this thread, i was at work and the majority of the pictures are blocked from most websites. then, last night/early this morning when i went to post again, i totally skipped the screen shots judas posted of CPU-Z and whatnot.

so...that would explain why the CPU temps are dramatically lower....sorry judas!!!

The Freezer 7 Pro is a pretty decent HSF - The Medion MD8383 (model before mine) was notorious for having a noisy stock HSF, and the Freezer 7 Pro was the main model suggested as a replacement.

Wonder how it compares against some of the latest and greatest HSF designs.

hey, i don't mind a little critisism.....however provided with the means, i won't pull any punches..



And there are 2 distinct models of the P4 Prescott 775LGA 505's, i've the newer one

Not meaning to hijack your thread Judas, but I was following along because I was just about to stick a Prescott 3.0 in my Intel board to replace the Northwood 2.8 that's been in there for 5 years............. then I realized your "early" Prescott was a socket 775 unit....... not quite as early as my 478 stuff.

But I did it anyways and the temps jumped dramatically (as was expected). I didn't have anything here that would keep it under control. Running at 55c at idle with my Aero cool, bios read that as 59-61c, I didn't even test this thing under load, I shut it down when bios temps hit 62c after just a few minutes.

I remembered seeing an Arctic freezer7 pro at the surplus store I go to..... in a box of junk HSFs, used, $2.00. So yesterday I went back to get it, if the fan worked. (9volt battery test ) It did work, I figured it wouldn't be that hard a mod to mount it to a 478 socket board.

Today I got some bolts/washers/nuts, did a little grinding on the freezer7 mounting bracket and stuck that deal on there. I had to trim the 4th wire off the power plug, there was a capacitor right there in the way, no biggy. I can hook that to a speed control some day if needed. Temps dropped about 15-16 degrees at idle.... running at 39c according to speedfan and everest home. Nice!!! Quite too.

Clean mod unless you hate the look of bolts, but you can't see them unless you're looking for them.

I'll fire up the DAW later and see what temps get to when playing a complex song......

Warmer than the Northwood, but manageable. I can take pics if CD's doesn't believe me

very cool.. could you take shots of the modded freezer 7 pro?

the freezer 7 pro's i've got my cost is over 35 bucks. so 2 dollars.. wow!

I just got another Prescott 775 3ghz.. it's much newer then the 2.66ghz model i was working on.

it's 64bit capatible as well.. (which is awesome as i thought it was 32bit only)

I beleive it's a 630 model.with speedstep.

All i know is that the stock cooler on it idles at 57-59*C...... the board looks like it got roasted pretty good, i had to replace the PSU due to the 12v 4pin connector litterly MELTING to the boards connector (the psu fried).... DAMN MDG.. you make shitty machines...

anywho... rock solid on a D945GTP motherboard (by intel)... interestingly enough i decided i'd do my usuall full bios update check and see what was available, the last bios update was in 2005.... however, RECENTLY, january of 2009 a new bios was released which provided additional features and such.

I'm going to yank the stock cooler off and see what's up, cause the damn cpu keeps throttling down due to the sheer heat. Going to try and convince the customer to put on something far better like the freezer 7, it's the cheapest cooler i can get my hands on that isn't junk.

See if i can get that bugger below 40*C

Maybe I shoud tweak my BIOS settings, on mine, the stock BIOS control setting for the CPU fan control is 60C - I guess they prefer to run it quieter, rather than cooler.

If yours is like that, then just tweak the BIOS setting and it will up the fan speed - callsic example here is that the idle is pretty warm with the fan at min speed, and as soon as it's hit with a decent load, the fan speed will ramp up like crazy.

i've already disabled the fan control and have it cranking out max... sounds like a jet engine with a 80mm fan turning over 5300 rpm... runs hot... with the fan control on.. the speed of the cpu in windows was roughly 1/2... i think the multiplier drops to 6x vs the 15x it should be (1200mhz vs 3000mhz)

Here's some photos that show the mod...... if I had a torch I would have brazed the top washers into place and polished it up but it's not necessary to do so.

If you think of the stock bracket as an X the bolt locations for the 478 socket fit inside the X. You need to grind a small notch in all 4 legs to clear the bolts and keep it centered on the CPU. I cut the rest of the stock bracket off to clear other components on the mobo..... there's no going back to using this for a 775.

Bolts feed through from the bottom, I used a large panhead bolt that fits the pads on the mobo perfectly. I have 2 washers an a nut on top of the mobo for clearance and proper downward tension. Those nuts lock the bolts into place so in theory they are now studs that the HSF mounts too. My setup fits pretty snug against the 4 studs....... I used a trimmed "fender washer", a lock washer and a nut on top and tightened it snugly without over tightening them. Lock washers keep it from backing off, but I doubt it's ever going anywhere.

Worthwhile mod in my case..... and yeah, $2 plus about $1.50 for the bolts and stuff. I know the Freezer7 pro sells new for about $30. Isn't surplus wonderful?

quite inventive

Under the top fender washer is a section of the original bracket about 1/8 inch wide by 3/8 inch long....... it ain't going anywhere.

I was just running my DAW (reaper) on this Prescott system, playing a fairly complex song (15 VST effects and 13 tracks) and it never got over 44c. System load went down considerably with this processor running my music software. So I put on media player, listened to "House of the Rising Sun" by Frigid Pink on one screen, and came to DH on the other screen, reloaded until I got 2 of the BFG ads and it got up to 51c at 75% load.

I can live with that ...... Other than mixing songs I don't use that system much..... So Freezer7 Pro on a 478 system works great.

Cool stuff Ty nice mod man

I may have to dig up some old pics I also had a Freezer 7 Pro on a Prescott 478 a couple of years ago.
(I misread that P4 didn't include 478 lol)

Actually I did a screen capture and then realized I don't have Paint or anything else to paste them into on that system...... so you're out of luck anyways.


When that same processor was in this HP with 512mb two of those ads would peg it at 100%, so Yeah! they are bothersome but not worth bytchin about. In this case a good "stress test" lol

What I did was pull the Prescott out of this HP SFF and stuck the Northwood in, runs cooler that way and performance is about the same for internet use and as a "stereo". Then stuck the Prescott in my tower and got a power boost there. So it was a "win win" situation once I got the surplus HSF installed.
