Ok i have amd athlon 64 3500+ and msi k8n neo2 platinium mobo. Here is my problem:

So before I installed my XP-90c cooling on my amd 64 3500+ my idle temp was 57-62'C ( IT WAS ON THE STOCK HEATSINK MY CPU CAME WITH )

I istaled my XP-90C with artic silver 5 and Antec 92mm Tornado fan and my temperature is STILL AT 56-59'C ! What could i possible done wrong? I heard something about artic silver 5 burning in and what now... but really RIGHT OF THE RESTART THE TEMP IS SO DAM HOT ALREADY?!

--I think heatsink may not be in proper contact with the cpu because its not very hot at the base or at all. But when i intalled I made sure that they are making contact by looking at disturbance on atric silver 5!

btw- fan is operating at 4700-4900 RPM

PS. MY CPU is at default speed 2.2ghz NO OC

Please help me!


Also, some info:


Here is what I check my stuff with

Temps and voltages:

again using different program

My bios version is 1.80 ( most recent )

- I did use A LOT of Artic silver 5, I got it all over the cpu and the heatsink. I put the HS but nothing came out at the edges. So yeah its way more then should be there.. could that be the problem?

Try taking off the sides of the case, and running the computer, to see if there is any change. If there is a decent change, you might need more fans for the airflow through the case (ie you are getting stagnant air in the case).

No change, also i have many fans blowing air in and out, air flow it great. ( Case is open now btw )


ps. If i go to remove my heatsink to reseat it, should I do it while its HOT or COLD? I dont want my artic silver 5 to act as a glue...

Too much arctic Silver can be the culprit I think. (why can't they make copper based thermal grease? :p )

They use silver, because silver is a better themal conductor than copper...
Copper (Cu) = 4.01 W/(cm*K)
Silver (Ag) = 4.29 W/(cm*K)

it is only used to fill in the micrscopic gaps between the two conductors (the hsf and the heat spreader) if you put too much it actually serves as an insulator.

Yeah, but how come? Doesn't higher thermal conductivity mean better heatflow in all cases? What am I missing?

so you guys are suggesting to remove my HS and reapply the artic silver 5? Also do i remove my hs when is hot or cold?

Well, you also have to consider the stuff that is in the thermal grease as well. They can't make it all silver. Say you have a mixture of 75% silver, and 25% silicone (I'm not sure what they use, but for conversations sake). If you apply the thermal grease, and it's only 1 unit thick, then 75% of the area conducts, and 25% doesn't. Now, if you apply it two units thick, you are going to decrease your conductivity twice as much. If you do this really thick, you are doing more insulating than conducting, because the other stuff is actually insulating the silver... Make sense?

NeoPL: Yes, it wouldn't hurt to try that. And I'm not sure about whether hot or cold, but I'm pretty sure that doing it cold won't hurt, as that is it's "natural" state for installation.

in an organized solid yes, as an unorganized mound of goop no.

edit: bad analogy

And yes, NeoPL, you should properly re-apply thermal compound to your heatsink. (report back your temp difference too ;))

Good point, didn't think about that.



Still, why can't they make thermal paste as conductive as copper? :p

(I will shut up now)

no need to hush, answers are free, a given solids metal thermal properties transfer better than a given liquid metal. Arctic Silver is a semi-liquid compound, this is one reason why it takes some 200hours and multiple temperature cycles for it to operate most efficiently, over time and with thermal changes it solidifies somewhat and conducts better.

Because it wouldn't be as pretty! ;-)

my temp is still high 50-58 ( thats after properly aplaying as5 ) I just hope it'll burn in or something.... i heard ppl with same set ups were in LOW 30's and im in mid 50's....

Neo2 --> VERY screwed up temperature sensors. Do a Prime95 Torture Test ("Maximum Heat") for 3 hours, if you pass it then youre temps are fine.

50C at 100% load isn't bad and 58C is a little high (depends a lot on room temp), what is your idle temp?

Pentium guy is right, it could be a defective sensor giving high readings, running any program at 100% for several hours stable should be enough to not worry about the temps

thats 58 at idle temp, there is no cpu usage. This program is just f up. After one and one heat cycle temp droped to 46. So I hope it'll jsut keep droping.

PS. I was running the prime95 for about 15 minutes and it only got up to 60'C while running my pc was almost unusable... like in a mud -_-

but anyway, is there anyway i should config this program or just click "Torture Test" ?

I'm running torture test, my cpu is at 100% load and my temp is constand 64'C , is that even safe?

Safe, but definately not recommended. The CPU will run at thoes temps, but it will also take damage over time.

what the hell should i do then? what the hell is the problem? It is not humanly possible to be at these high temps with the XP-90c cooling and no OC what the **** is goin on here?!

I stoped this prime95 and temp is at 50'C IDLE TEMP 0% cpu usage... wtf.. this is way to hot too... I just dont know what to do at this point...

I also have high temps. 3200 venice core, stock speed and I get 55-65C in the BIOS or in windows @ idle with the case off in a 74F room. I'm running foxconn nforce4 board (I RMA'ed this once for this problem and erratic boots) and a zalman 7000cu (w/ zalman's thermal grease). I've remounted the CPU several times, tried different BIOS versions. I'm only running a 300W antec 20pin PSU to this board. Can weak PSU's put strain on the CPU causing higher temps?

I've disabled CPU throttling as it causes everything that's CPU intensive to stutter wildly.

On my Neo2, my A64 3500+ Winnie runs 33C idle-47C load

On my K8NS-Ultra 939, the exact same processor runs 30C idle-39C load in the same room.

I'm running the 1.8 BIOS on the Neo2, which sorta fixed the temp reporting, but the Gigabyte is still better at it...
