CPU Temps: is 61 deg C too hot for P-D 820?

MadMax350 · Post by **MadMax350** » Tue Nov 22, 2005 11:41 pm

Just built this system recently and installed 5 case fans. Using the Intel Pentium D 820 2.8ghz dual-core. I have heard these things run pretty hot but I am curious as to how much is too hot. Playing most games I have not been able to get the CPU temp to go above 58 deg C but I just decoded a DVD which put both cores to 100% use and after about 3 min the temp climbs to 61 deg C and hangs there. Idle temps are about 47 deg C.

So what do you guys think? If I need a better CPU fan and heatsink, who sells good ones that will work with this dual-core processor?

Thanks in advance.

Seems very hot ... I run BF2 for 3 hours straight and I barely approach 40c

might wanna peal apart the cpu/heatsink and try some arctic silver thermal compound ...

i'm an idiot though so i'd wait for a second opinion

Thats not extrodinary for that CPU. What is your ambient temp? What case do you have? If your really worried though I would check airflow in the case (make sure the fans are pointing the right way, clean up the cables etc.) If that doesnt give you the desired effect try a zalman 7700 http://www.newegg.com/Product/Product.a ... 6835118115
Thats what I have on my 775 CPU and i idle at about 36-38 and 53-56 when gaming, ambient 35(It is cold out though). When I had the stock cooler on I was right about where you are. I've also heard good things about the xp120 from thermalright.

yeah I agree thats not too hot...but I'm like izzo.. i'd look at taking off that thermal pad which came with your HSF and replace it with some artic silver thermal compound..that stuff works great..that alone may drop your temps 10c!!!

61 is no trouble, good for warming the room up too, think of it as a multitaksing space heater.

Its not out of the ordinary to have two Prescott's (preshott!) up in the 60's. You should be able to get it down in the 50's though, just do whats been said earlier. Prescotts run hot really no matter what you do, its just how they are designed (unfortunately).

Thanks guys. I am going to look into getting that arctic silver and if that doesn't help matters much I will get an aftermarket cooler.

Upgraded CPU cooling device to a Thermaltake unit I got from a local computer parts retailer for $41.00. Also used the Arctic Silver 5 compound. Highest I see CPU temps getting now is only 42 deg C. Certainly much better than the 60+ deg C I was getting with the stocker.

The new cooling device has a copper heatspreader that has 3 pipes coming off of it attached to what appears to be many stainless radiator fins. It came with an oversized fan which does have a 4 wire connector but appearantly it is set up to run at full speed only

so it is a little on the noisy side but not bad. I will put up with the noise for now. As far as overall size it is considerably larger than the stock Pentium D 820 fan but I wouldn't go as far as to say it is twice the size, probably on the order of 1.4x so not bad.

As far as how it attaches to the board it uses a plate that goes on the backside of the mobo that it screws into. The screws are spring-loaded as well. Quite honestly I like this design MUCH BETTER than those dumb pushclips that came with the stocker because you can't really screw this design up. I didn't even have to remove my mobo from the case because my case has a small opening behind where the processor goes that allowed me to hold the plate against the mobo with one finger while I was installing the cooling unit.

Thats almost unbelievable with that core on air cooling if that 42c is a full load temp.

Yea, that seems about the norm idle temp, not full load though. gotta remember that most sensors are off a bit, so its probably loading in the low 50's which is normal.

Sorry guys, the front panel temp reading is off a few deg and that was what I was basing my new readings off of.

I loaded up Windows Task Manager and Gigabyte PC Health Hardware Monitor (windows-based software utility) and re-encoded a DVD again which maxxes out both cores and ran that for about 10 min, the last 7min of which the temp didn't change. According to the hardware monitor program, the CPU temp never gets above 50 deg C (front panel was reporting 42c, so it is off quite a bit). Idle temps are around 33 deg C. I haven't taken an internal case temp but it doesn't seem much above room temp of 70 deg F.
