cpu temp 50 degrees celsius at idle.
« on: 04-December-03, 13:12:05 »

hi, i think i need some cooling..
the temp of my cpu is over 50 degrees celcius at idle, and i am getting worried.
i have tried some coolermaster jet 4's on my system, but they have to be cranked up full throttle and still only bring it down to 50 deg celcius..
i use a high powered exhaust fan and hdd cooler collermaster cooldrive 3.
at mo i have gone back to pentium's heatsink and fan as it is actually quieter and as good as coolermaster's. but i need to get the temp down about 20 degrees!!
funny thing is at high stress the system only rises about 6 degrees, but i would like the chip to last longer than 12 months, so any ideas about some good coolers??

Check your thermal paste first. Get some good paste and see if it does the trick.

Yuo are welcome. Try Arctic silver

daffy the red;
I agree with the Artic Silver use.  I also am using a Zalman cooler.
Now idle temps are about 40 C and case temps are 35 C.  This is a big improvement from the stock HSF that also gave about 50C temps for me and up to 60C under loading.

If you're using a BIOS before 1.4 the reading will be 7-10C too high anyway so you could just forget about it/take that into account/upgrade your BIOS

....also enabling Hyperthreading will reduce your CPU temperature

It could also be that you havent got enough air flow... just having a very powerfull exhaust fan is not helpfull if not enough air is getting into the case in the first place (air out = air in), your exhaust fan will just compete with your PSU fan for the available air and could actualy increase your temperature by over heating the PSU

hmm, cheers, as present i am on bios 1.8 and unfortunately HT won't run on my pc, crappy ram you see...and even worse, i can't afford new ram till january.. ;-((
i thought about zalman, but wasn't too sure about the extra weight. look's like i will add one to my pc wish list along with some arctic silver and bios 1.9....
comeon santa..

Daffy, I was equally concerned about the Zalman 7000 Cu model and opted for the AlCu model.  Almost half the weight and a great cooler.  I do not overclock, but according to Speedfan my temps are 28C idle and 41C load via Sandra Burn.  I had a Aeroflow, but the noise and vibration (I think due to the TMF design) was too much.  The Zalman runs very quiet.

I think someone forgot or didnt realize they needed thermal compound between the CPU and any Heatsink.  :nono:

lol, no i did use heat compound, just the one that came with the processor..

thought l would update this thread rather than start a new one.

I am getting idle temps of 44-46C. I suspect this is too high.

The reason this is concerning me is my fps in doom3 is only 22-25fps when running the time demo demo1.demo. I have doom3 set to 1024x768 with high quality. And l suspenct the P4 thermal monitoring is kicking in and slowing the CPU down. I have applied the ati doom fix and spent hours tweaking with cvars.

Do you think l should re-apply the thermal grease on cpu and zalman?

thanks in advance, Nicholas

Well my rig is at 55-56°C Idle and jumps to 69-70 at full load, but never goes over 70. And thats hot. :angryfire:
So I wanted to ask the MSI staff, when are you going to release a new bios for the 925X MOBO, as Im pretty sure the problem lies there.....

thx for the comments dingo. but ur P4EE and my P4 HT are like comparing chalk and cheese.

I've heard those EE's run pretty hot.
