I'm running a Pentium D 840 3.2GHz dual-core CPU in my system, and with the fan that came with it it was running extremely hot, like in the 80's celsius without doing much of anything. SO I got a new fan - a Zalman CNPS7700 all-copper cooler. I'm also using Artic Silver 5. With the fan on max speed, the CPU still gets very hot - with a load, it will rise into the 70's C and start to climb just over 80. I've tried remounting it several times, using different amounts of thermal compound, but still it runs hot. Any suggestions?? Please????

I actually read on a website that people were overclocking the 840 with the same exact heatsink, and I'm not even overclocking to get these high temperatures. Right now I'm running with only one core enabled to prevent it getting too hot.

I had a Prescott that ran just about that hot.
Case fans have helped, actually. So I suspect the problem is that these CPU's dump so much damned heat that they heat up the whole case and the heat doesn't evacuate fast enough with only one case fan or none at all.
With 2 fans in the system, the temp only gets about as high as 75° under typical high-load situations (I idle at about 47° when I'm lucky). That's actually supposed to be the norm for these CPU's, believe it or not.
So yeah… get yourself some casefans and make sure you have proper airflo through your case. This may require tucking away loose IDE cable somewhere or getting a round IDE cable – those ribbon cables can be a real bugger against air flow.

The thermal specification for the hottest point on the die on average for optimum performance is around 70C - 80C for a Pentium D 840, your running average not over temped. You can usually average a processor out by 10 Degrees over what the Thermal specification for a processor is because they benchmark different then an average computer does. Things like cases, poor air circulation around the computer (due mostly to enclosed computer desks, low sitting computers (keep it off the floor) and so forth,) equipment running in the computer (this can help rise the temp of the die because they create heat as well) when your Pentium reaches an average temp for usage of around 95C you need to start worrying because then it is overheating, you should start to wonder at about 90C other then that you are a running alright.

generally the thermal paste is used to maintain the warmth conductivity substitute between the CPU and the warmth sink as effective as achieveable. whether the extra you utilize, the fewer effective it gets. Realistically you ought to use a skinny layer on the right of the cpu chip in basic terms the place it contacts the warmth sink, then fasten your warmth sink/fan and pass away it. Any time you're taking the sink & fan off you ought to use the comparable quantity, provided that the chip needs it! in case you think of your comp may be working too warm, my first suggestion would be to function extra followers. you in all probability have a CPU fan, a video card fan, a capability furnish fan and a rear of the case fan? you will try including a fan to the front of the case to pump cooler air into the case. additionally (in the adventure that your case is closed an outstanding variety of the time) you will take the main significant factor panel off your case and positioned a small room fan blowing promptly in. Or considering stressful drives generate an outstanding variety of warmth and no-one thinks to chill those... perhaps upload a fan on the right of your case to pull warmth off the CD/DVD drives and the tensechronic so it does not merely upload extra warmth to the interior computer ecosystem. If that still isn't sufficient, you could would desire to look into liquid cooling on your device, or a form of latest a/c + dehumidifier instruments for comps now (with reference to the size of two 5.25 floppy drives, needs its very own capability furnish yet extremely clamps down on device warmth). That'll run you approximately $six hundred - $800.

Look into a Zalman CPU fan, or liquid cooling systems. Use "Arctic Silver" thermal grease if you use the Zalman fan. This stuff helps reduce the heat also. There are also "Air Conditioned" cases out there, if you've got the $$$.

you have poor airflow
keep in mind pentium chips do run hotter than amds, but 80 is way too hot..
you need to see what type of airlfow you case doesn't have and ajust according. i just set up a mid tower with a amd 4800+, 2gb ddr2 ram, a 7950gx2 videocard, 550w psu, 4 drives. of chief concern was the heat, since the viode card along drew 85 watt, the cpu 128 watts. neatliy sleeving all of my cables, going with a modular psu and adding 4 case fans ( and still working on one big 120 for intake in front ) has both my cpu and my vid card temps in the low 40s.

Pentium D's runs hotter the other CPUs. You will have the either add more fans or try to make sure the air for in your case is moving properly.

p D uses alot of power than an athlon 64 chip and creates alot of heat, check the airflow with the heatsink and the other system fans

Sell the damn Pentium D and buy a Core 2 Duo (Conroe) it will save u from lot of trouble. If u are a game enthusiast go for a AMD. that will be better.
