Maximum acceptable temperature for Pentium D?

[clickynext]

I just noticed that my Pentium D 805 seems to run pretty hot, even for a Pentium D. Right now it tends to idle at 60c, and go up to 75c at load. This is stock cooler, stock clock speed, in a decently ventilated case (a bunch of case fans running at low speed).

Are these temperatures normal?

Seems high, even for the dreaded stock cooler.

All 4 pins of the heatsink firmly engaged and locked?

Heatsink fan and cooling fins clear of dust/debris?

With stock cooler, stock speeds:

At stock speeds (2.66GHZ, 1.3V) the Pentium D 805 ran about average, temperature wise. At idle I recorded temps between 41C and 43C during my testing. Under load the Pentium D 805 reached a warm 59C to 61C. For someone who won't overclock or run this processor 100% load for days on end, those temperatures are fine.

Thanks NXIL, you've been very helful in answering a lot of my questions lately!

I think they are, I checked them to when I installed the proc to make sure they were down flat and secure, but the stock cooler is a terrible design IMO! It took forever for me to figure out how to get the pushpins ready to insert, and then it was impossible to push them down 2 at a time like they recommend.

Maybe I'll have to reinstall it. I remember this thing idling in the 50's when I first bought it, about a year ago, installed into a different mobo.

Motherboards might report different temperatures too.

Thats not normal temps for stock speeds, even on the stock heatsink. Your idle temps are about what your load temps should be. The pushpin design is horrible, it can seem like it's fully seated and locked in place even when it's not. I recomend removing the heatsink, clean off the thermal pad, and re-install it using artic silver 5.

Heh, it already is on AS5.

I think I'll probably sell this thing when I bought it, it was for the cheap overclock, but now I can't even overclock it (because P35 mobo can only do 200mhz fsb minimum). I guess it's time I moved up to a core2 based processor.

You could always get a better heatsink. My 805 has been running at 3.6ghz for about a year now with a scythe mine, and thats not even that high end of a heatsink. It's still no core 2, but a 1ghz overclock on a cheap heatsink isn't bad.

I think that's about right on an 805. I used to have one on a arctic cooler pro and it reached about 62 on load on prime 95. On stock, 70 sounds about right.

I've often wondered whether it's better to spend money on a heatsink, or to put that money to getting a better processor. Scythe Mine (and most decent hsf's) cost $40 where I am, which is the difference between an E4500 and E2140.

Something tells me the extra cache would yield more performance than the extra overclock.

According to this article, every jump in cache is equal to one jump in speed:

http://www.tomshardware.com/20...oes_cache_size_matter/

Conclusion

While cache size only had a limited impact on the synthetic benchmarks such as PCMark05, the performance difference in most real-life benchmarks was significant. This was surprising at first, because experience tells us that performance differences can typically be found in most synthetic benchmarks, while little of it is eventually reflected in real-life benchmarks.

If you compare the benchmark results of the 3D shooters Prey and Quake 4 with typical gaming benchmark results in our CPU Charts, the performance difference of 1 MB vs. 4 MB L2 cache roughly equals one clock speed increment.

OK, I shall refrain from any "size matters", "it's so big" sort of attempted humor...really.....

It depends how hard you overclock. The stock heatsink and fan are usually good enough to overclock as high as possible without changing the voltages. My current processor is a C2D 6600 with a stock heatsink and it can be overclocked about 30% at stock voltage with a stock heatsink (3.1ghz from 2.4). Before that I had an Athlon (Barton) 2500 that was overclocked to the 3200 speed, using a stock fan at stock voltage. The CPU might be hot all the time, but it's stable as hell. A constant 70C (running F@H) doesn't really mean anything if it doesn't cause crashing and doesn't damage the hardware.

If you already have a heatsink, just get the faster chip. You won't need a top notch heatsink unless you plan to overclock the chip to ridiculously fast speeds.

I don't have a heatsink already, planning to use the stock hsf.

I wonder if the E2140 would hit 3.0ghz with stock voltage? I know if it's a huge jump, almost 100%, but considering the reputation of these chips...

They mentioned bumping the vcore to 1.525v to achieve that, though! Yikes!
