New to building computer...is CPU Temperture OK ?

Hello,
I am new to building computers and I was wondering if my cpu temp is normal.

I have an DFI Lan Motherboard Pro 875B.
With 240 GB Hardrive
BFG Nvidia 6800 OC Video Card
P4 3.0 Ghz Prescott HT CPU
1 GB Ram

My normal temperture is running at 55-60C and during gaming it is running at 65C - 75C...

Is this fine ?

Thanks
 
Well, I'm not really an Intel guy, but I'm pretty sure that's wayyy too hot. You might want to consider checking your thermal paste to see if it's dried up. Someone I know last year had a similar issue where his temps went that high. If I'm not mistaken, Intel chips usually run cooler than AMD and anything over 70C for an AMD chip is way too hot. Also, check what you're using to get the temp readings. Try MBM5 and see if it says the same thing. Either way, those temps look really high.

Well, high or low temp are relative, especially here when you have people with varying standards on what they consider "acceptable" temps.

Your temps, however, are DEFINITLY on the high side. Not as high as I have seen, but very close to it. What case are you using? What is your cooling setup for the case? What kind of heatsink/fan do you have on that P4? are you overclocking at all?

I don't know much about P4 temps, but when my AthlonXP hits 60c under load I know that is way too high, and that only happens in the hottest part of summer, my load temps now are 45-49!

If you have not done it yet I would open the side of your case up for more air (and more noise) until you can figure out why the temps are so high. It *could* be that the temp readings are just faulty, check your BIOS readings and see what it is saying.

That 75c is way up, limit for a P4 is something like 90c on core and with most temp monitors you need to add 10-15C to them to get the actual core temp so you are pushing your limit...

I am running two P4 intel xeons, and 70 is way too hot, like spike said, you should be running at the warmest high 40's. Perhaps you need another fan in yoru case. Do you have the rear fan attached that sucks air away from the HS? Do you have a front fan drawing air in? Unfortunately, the really important info is what HS you are using, and did you use thermal paster, or just smack the heat sinks on? Are the fans on the heat sinks spinning? I would assume you have 1 of two problems. Your HS is not properly mounted and therefore runnign temps high, or you don't have a fan running near the HSs.
 
Thanks for replying guys.

I am using a aeroflow fan+heatsink...

The cpu fan is running at 4400.

I also have 2 side fans on my case, the cpu fan , and the power supply fan.

That is it.

I did use thermal on my old motherboard but since the motherboard crashed, I had some thermal paste left on top of the cpu, so I just mounted the heatsink on top of it and went from there.

I was thinking that since the paste is still on the cpu it should be fine.

Let me know.

Thanks
 
NO GOOD!!!!

Shut down the computer and remount that CPU and HSF.

Intructions for applying thermal compound

Follow those intructions and try again, you should see a dramatic decrease in core temps. Make sure you clean off both the CPU and the HSF before applying it again, you only need a thin layer. ANYTIME you remove a HSF from the CPU you need to redo the thermal compound, regardless if it is only off for 5 seconds. Try this and let us know what the temps are looking like.

i did not like those temperature either, BUT i never had a problem, I just always wondered if it is too hot if Intel says the max in 73C, i thought like well, that is mighty close....

I went to water and built one external to the PC and run a tube to it and a tube back to the radiators.
you can get lucky and score a cheap Iwaki or other pump under $100. I got an Iwaki for $46 plus shipped.I got radiators for $20/pc. and made a reservior out of PCV sewer pipe to fit my plan, a box of wood under the typing table the PC is on,,,,,you could put the stuff in an old rummage sale side stand table like granny had, whatever--i made a box of woodlaying around the place--or you do not have to have a box---i had to have a box with the radiators on one side air tight to pull with a fan to move th air...you get it...use you imagination

i run a 120v pump and 120v fan with a relay off the PC so it turns on with one button....you can turn the cooler on first or whatever....but the water cooler has to be on
 
I don't think anyone is steering you wrong, saeapu, but I thought I'd add about two cents worth. I looked up your mobo, and it IS a socket 478 for your Prescott, but I still think the temps are way, way too high.

Also -- somebody else may have noticed -- you said you left USED thermal paste on the processor? NO CIGAR, DUDE! Unclip that heatsink and go again. If possible, get a clean cotton rag and some 99% isopropyl alcohol, dampen the rag, ground yourself and clean off that processor cap!! Then put some fresh paste on it and try again. People may laugh at me, but if I can't get 99% isopropyl I use 12% rubbing alcohol and clean carefully.

I'm still trying to see if I can get my core temperature down a notch -- looking into variations on Sentinel's ducting mod (See "Foam Board Mod"). Scoping out the Home Depot for plexi-glass -- tooo - daaayyy!!

Sucking the dust out of my filters, my Northwood 3.0C @ 3.6 Ghz is idle at 82F and 100% load value is 103F -- removing the filter from the CPU fan would probably knock that down 2F to 4F, and I have some tricks up my sleeve before even trying the flat-panel duct.

I KNOW Prescott's run "hotter", but the thermal limit is not above 70C -- check the INtel web site. Something very wrong with any combination of CPU heatsink installation, case ventilation, etc.

 
If you use the link I provided above that should help you in cleaning/reapplying thermal paste. You can use rubbing alchohol as Bonzai suggests, I personally use Goof-Off and a lint-free eye-glass cloth to clean my cores. Both can be had for less than $5 at a drug store

Thanks For all your help.

I will give it a shot.

My motherboard did not come with a cpu fan checker software.

Is there a free one with no bugs or virus on the internet that I can download to see my cpu temps ?

Thanks
 
Motherboard Monitor is one that will do the job. You'll need to tell it what mobo you have, though, which is where some people get mixed up. If you want one that will give you those items, but a hell of a lot more, look at Everest (www.lavalys.com)...
