Pentium-D stuff

**shocky123** · 10-26-2005, 07:28 PM

Anybody else having or heard of someone having significant thermal problems with the Pentium-D's?

I have a P-D workstation and I'm concerned that it hovers at ~65-70C in bios.

I am also having major problems with a Dual Core Pentium EE (Dual Core Pentium w/ HyperThreading).. it idles around 72C in Windows. This overheating is so bad that the thermal alarms go off (79C+) after about 45 seconds of benchmarks that push/stress all 4 threads.

So I guess I'm wondering if this is mostly due to fatal flaws in design and excessive clock frequencies?
Anybody have links/reviews/articles that address this and/or propose solutions??

Bires had a similiar problem here.

He's apparently done with the Pres-hots.

If you realy want to try and save it, I'd suggest you try watercooling with one of the better commercially available kits out there.

My Prescott doesn't get that hot...

Maybe it depends on what kind of cooling you are using on it and how hard you are trying to push/OC it.

I ran Prime95s "torture test" for 8 hours straight last night and the hottest it got was 45C...

Maybe my "Coolermaster CMS Stacker" case with 3 120 mm fans has something to do with it... or maybe its my Zalman Cu fan/heatsink combo? Either way, I just don't have heat issues with my Prescott (which was purchased from ZipZoomFly in a retail box)

I use my Prescott 3.4 to heat my home office. Seriously! I never have to turn on the heat in here during the winter. But I've never had a shudown situation... something about the heat sink from hell with a pair of mondo whompus fans pulling air across that huge heat sink - and another pusher to keep air coming into the case.

supposedly it does double as a space heater. also, the stock fans that come with prescotts aren't really worth keeping. zalman as a new amazing heatpiple cooler you could be intrested in, although it is pricey

WOW! Nice cooler! On mine, there is already a heat pipe cooler - which had to be upgraded under warranty as the original was not sufficient for the job. As soon as the ambient temperature in the room hit 75F, the fans started to blow significantly harder and harder due to CPU temp issues. The new upgraded heat sink took care of it. Still a space heater, but the fans aren't running as fast. Got a little noisy!

yea i'm running crazy hot, look at these stats, i have nothing running except for trillian and one instance of IE

**DarkFury** · 10-28-2005, 11:40 PM

Well these readings were taken after playing City of Villians for 2 hours...

I think you guys need better heatsinks/cases for airflow... or maybe it's just a problem with the 3.0 GHz chip.

this was idle for 5 minutes man

**shocky123** · 10-29-2005, 04:09 PM

Was that on the Dual core version ??

I know there is a thermal throttling that the P-D does that slows down the clock of cpu2 (cpu1) to decrease the overall temp of the cpu.. so it effectively runs the whole cpu at lower speeds, but doesnt show it to the operating system.
Seen any of this??

Yeah...

Basically what I'm saying is... "why is yours runnin' so hot?"

Must be something wrong with the 3.0s

**Burzhui** · 10-29-2005, 11:03 PM

i dunno maybe, maybe it's just the stock sync, last time i upgraded mine , my comp started sounding like an air craft carrier

**shocky123** · 10-31-2005, 09:30 AM

Are we thinking this is a heatsink issue, or a thermal compound issue ?? Airflow is not likely the case, the EE chip has beyond reasonable amounts of airflow and still runs way too hot. If this is looking like a heatsink/compound issue, would the next logical course of action be to pry off the heatsink, shave off the thermal compound and reapply some of the best stuff I can find? ~Kyle

Personally, I'm using Arctic Silver 5 and this Zalman cooler:

BTW... what is your inside case temp?

Mine is a single core with HyperThreading...

They don't make a Dual core on the 478 pin architecture... the Duals are only on the LGA775 architecture.

**shocky123** · 10-31-2005, 06:19 PM

Yeah, I know heh they dont make the duals on the 478 pin chips.. I was sorta under the assumption that we had established that already.

Inside case temp is << cpu temp ...
case temp on my workstation is like 30C max..
and the EE box is less than that.
Arctic5 is the way to go.. its what I use on my stuff, these chips are at work though, so they have stock heatsink/thermal compound as far as I know...

I still havent been able to pry off the stock heatsink on my workstation, it has some weird plastic twist-plug sorta thing thats supposed to lock it into the other side of the mobo through 4 holes around the cpu mounts.. but I couldnt get those stupid things out for the life of me..

Does Zalman have a heatsink for the LGA775 chips?
..preferably one that's specifically made to keep the frying pan cool?
