PC temperatures

Andretii

Hello everyone. I just overclocked my PC trying to get more juice out of it and I'd like some advice on the temps I'm getting from it. See the following SS and let me know if they are too high. Thanks

Are those idle or under load temperatures? Modern CPUs can operate just fine at 80C, but if those are idle temperatures it's going to over heat when you do something resource intensive.

To check if it's stable, run Prime95 for a while and see if it crashes.

They are idle temps. Just ran CSS stress test and then they went into the 80s. Gonna run Prime95 now.

thanks for the replay

If you have a newer processor(65 nm or smaller) that seems too high for idle, even if you have it overclocked. My quad core Q6600 idles around mid 30's C at stock speed.

It just crashed at the 3rd Prime95 test. Temps were at 100sC . Just changed the overcloking for 200mhz less.

I think i have bad cooling.

1 dumb question. Should the fans on the side be getting air in or taking air out?

The temperatures you've got are way too high considering it is idling. Go look up the datasheet for your CPU and graphics card to see what the limit for temperature is. Anything over 40-50 when idling is way too much.

Not any recent processor I've seen. The Core 2 Quad that the OP is using has a listed maximum temperature of 62.2C according to the Intel datasheet. 80C would trip the thermal protection mechanisms.

He probably has a P4. Those things run hot as hell.

EDIT: Nevermind. I see has a Q6600. In which case, 72 is WAY too high.

It says Core 2 Quad Q6600 in the screenshot. They're not supposed to go over 60C assuming stock voltages and reasonable cooling.

Are you cooler when a fan blows on you or away from you?

Depends, am I stuck in a hot box? If so, I want the fan to push the hot air out.

im driving a 21" LCD, a 25" LCD, SIMS3, and browsing the net on the other. Also, running a pair of 10,000rpm RAPTORs for the OS, and two Western Digital 7200rpm 1tb Caviars for Data, and two DVD burners. These are all $5 120mm fans. idle all cores <37-40C. 8800GTS ~70C. Running blend test on Prime95 rose cores to 50C.

i dont know how you have designed air flow on your case. remember that hot air rises. my power supply is on the bottom back of my case COSMOS. This case has good raves and i know it will last me 10yrs like my other cases. Its (PS) intake fan is on the bottom of the case and air comes out with its built in exhaust fan on the rear of case. hottest parts of the machine are the hard drives (other than GPU) so theres a built in intake fan under them, and placed another on the front of the case for intake purposes. 8800gts has stock fan. chipset has stock fan, so does CPU (yikes). Case also has built in two snorkel fans on top of the case.

ps, illustration on the site above, click on About, then thermal, good stuffs. i like how filters are easily cleanable. sides come off so easily, thumbscrews, quite HDD mounts, etc.

You should get a professional heat sink for your CPU "if you have a professional Case".

The Q6600 works just fine @ 80 degrees, I had my CPU running on 100% load for days "Folding@Home" @ temps around 80 degrees without any issues.

Changing the case to a full tower professional case "with professional fans dropped 5 degrees.

Changing the CPU Heat sink to a professional "V" dropped almost 20 degrees .. so now at full load I'm running @ 60 degrees.

i ran with stock as i built a dozen of these quad cores at work and they wouldnt justify purchases of "non intel" fans so i stuck with it... ive ran swiftech on previous amd's back in the day (not cheap) and that was great and see theyre still in bussiness

which cpu fan you running or recommend?

Intel still state that it is designed for a maximum of 60C. Any higher and there is a chance that you'll damage or reduce the lifespan of the CPU. 20C higher than the Tc temperature and the thermal protection systems kick in which usually throttles or shuts down the CPU/core.

You shouldn't be getting a CPU temperature that high anyway. If you have temperatures like that then you've got heatsink or airflow issues somewhere. The TDP for a standard Q6600 shouldn't push it to 80C unless something is wrong.

As others have said your temps are too high. Make sure you have a good heatsink and fan on your CPU and the contact between CPU and the heasink is even and precise. Apply the thermal paste sparingly and dont put blobs of it on.

About the fans - The idea is to keep an air flow through your case. This means bringing air in from somewhere and then forcing it out at the back. This keeps a constant cooling on all your system parts. Also make sure you use cable ties to keep cables in place and keep the air flow moving, a smaller case means less room to work in as well, bare this in mind.

You will need better cooling if you want to overclock your CPU, at stock speed the stock heatsink is more than enough.

I'm using V8 - Cooler Master

It is Huge and you will need a full tower case to be able to use it.

The problem is the average temperature around here at this time of the year is around 40C .. so 40C + CPU working @ 100% load 24/7 will get you up to 80C.
When I stop folding@home temp drops to around 45-50C
"I never had the system shutdown due to thermal protection"

now with the V8 hopefully I will have longer CPU life

o.O Oh yeah. That'd do it! With temperatures like that, I think I'd shutdown if I had to do hard work

Not to derail the thead, but Lamini, I don't know if I should feel proud or ashamed that I know what your avatar represents.

Yep that's a tad warm for idle. I'm using a Tuniq Tower in my rig, though I had to lap (wet sand) the base of the heat sink to get it cooling decently. I've got a E2160 OC'd to around 2.9 GHz and it idles around 30c. The cooler is really tall though, it barely fits in my Cooler Master Mystique case (best $40 I ever spend on a case, and it's aluminum too)!

Andretii

Please remember that those are IDLE temps while Overclocked from 2.4 to 3.2ghz.
I decided to fix the cooling issues of the system in the following months and then we'll see. I'll update this post later.

Thanks everyone for the responses.

BTW. My case is a huge, heavy CoolerMaster with a lot of space 2x120mm side, 1x120mm back 1x120mm front. The processor heatsink is a very good one, or at least the ratings I remember where high 2 years ago.
