CPU Temp?

friznit · Post by **friznit** » April 15th, 2007, 14:52

I'm running a non-clocked Intel Pentium D 3Ghz Dual Core 800FSB chip on an ASUS P5WD2 mobo with a mother of a heatsink and 3 case fans. CPU temp is idling at around 65 deg and spikes to 75 on light use. Since I put an 8800 GTS in, I think the ambient temp inside the box has gone high enough that under heavy load the cooling can't keep up. After about 30mins of play with heavy graphics/cpu load (e.g. ArmA/MTW2) the computer shuts down, presumably to prevent chip damage. At least, I think this could be the problem, unless there's something up with the graphics card which is causing this?

I've just jury rigged another case fan to blow directly over the heatsink and gfx card and opened a hole at the back to get more airflow going (and cleared some dust out), but short of liquid cooling this fucker (which is nuts for a home computer) I'm not sure how to get things any cooler.

Anyone heard of similar problems?

Are you using the stock CPU cooler?

My machine does this too kinda, but only occasionally and after 4 or 5 hours of Oblivion (my machine is an overclocked Prescott with an overclocked 7800GS in a Shuttle, so hardly a low-temperature environment). My CPU temps are maybe 5 degrees lower than yours, though.

sounds a tad high to me.

pull the heatsink, clean stuff and refit with proper heatsink goop

It might also be the case. A good case has a fan drawing air in the front/bottom and out at the back/top, otherwise you are just circulating ever hotter air.

I have a CoolerMaster case which will overheat if I don't clean the front air filters.

You might be able to set an alarm in the BIOS also to give you 5 deg c warning before it shuts down. Mine does this so I know to quickly get the hoover out.

Coolermaster case and coolermaster heatsink. Only started doing it recently, so it could be a combination of dust build up and the new hotter environment with the bigger gfx card. I'll try pulling it out and cleaning it all up a bit and see if that works

It's possible the longer graphics card is having a bit of a wind-tunnel effect, stopping clean air getting up to the cpu so easily.

All I can suggest is bigger fans and pimped out heatsink/fan combo's for the cpu AND the graphics card. And if possible, something else covering the northbridge (mine runs quite hot).

Even then though they're kinda high, the chips will take more than that, most will happily run at about 90c, but the mobo will shut it down to stop temperature running too hot for a long period.

My current runs (note: tis slow and oldish, new setup over the coming month or two) dual 80mm's at the front, single 80mm at top of case, and one at the back.
80mm over a rather rad coolermaster heatsink, aftermarket cooler for my ATi X800GTO AAAANNNNDDD a 80mm zalman floating fanthinige over the northbridge/cpu.

hoover the entire case, i generally get the long firm nossle that usually comes with a hoover for cleaning those hard to get to places (like berk's bum)

Nooooooo! They generate shitloads of static and noise and can turn your dirty machine into a very clean nackered one. Air dusters don't cause electrical or static problems and you can turn them upside down and freeze stuff with them too.

That

Can be okay for getting the big clods of fluff out, but i don't do it.

Yeah,

that, very hard, as Berk said.

Only problem with air dusters is that they're a lot of fun to use, and therefore in my hands their average life expectancy is about 5 minutes; at that rate, they aren't cheap. Also, trying to dust an entire house with them DOES NOT WORK.

But who can resist? They're like the duct tape of the compressed-gas world.

\starts thinking about combinations of duct tape and air cannisters. And cheese.

i have a handy dive cylinder for my air rife.
4351 psi is enough to blow the hair off your balls let alone dust from a fan or two.
Plus it makes an awesomely loud screaming roar that freaks things like cats and children.

never affected any of my computers... just make sure u don't touch anything with the end of the nossle... oh yea and do not succumb to the fun that is spinning the fans using only the power of the vacuum

we have a crow scarer which freaks out everything.. tis a tube with a gas canister attached, slowly releasing the gas over an hour then igniting it... so tempted to stick a spud to the end of it

Are you sure? I think we need Berk's help to test, although given that he edited my initial post to nominate me, I think he may be less than keen.

Whoever it is, the more i think about it, the more i feel it needs to be tested.

Oh so fucking this.

The hours of fun I have had sneaking up behind a mate at his station, inverting the can and giving him a good blast on the back of his neck (also works with just-removed-from-hot-beverage tea spoons, although this often incites a more aggressive response).

I'm sure there are a few strike throughs in that statement
