Hi i am running a p4 3.0 prescott on a DFI 865pe infinity board and right now just surfing the net with no background programs running its 60C. When gaming it goes up to 70. I am currently using artic silver 5 with a thermaltake spark 7 runing at 6000rpm and stil it dosnt drop much. the room temp is about 26C, the cpu use to be cooler, about 53 when not gaming during the winter. What can I do about this? I've read many forums about prescotts but havn't seen ones that are this hot on idle. Please help, thanks
 
Theres not much you can do really aside from getting a quality watercooling setup if you want significantly reduce temps. How is the airflow in your case, are cables cleared up? multiple case fans running?

With my system in sig I'm idling in the low 50s and im pretty sure im breaking 70C during gaming. Thats up from idling in the late 40s and settling in the mid 60s whilst gaming during the winter months. All this with a thermalright sp-94 hsf and thermaltake xaser case with 5 fans. My room temp now would be similar to yours (~25C).

Note: at stock speeds (2.8ghz) my temps are way lower, 45/55C idle/load.
 
Woah thats a really really high idle for the chip. I have the same kind of cpu with a stock hsf and silver artic 5 and my cpu idles at 38 and loads at 48-50c. I don't have AC in my room but then again its starting to be winter here in Texas :p. I'd check the mounting of the HSF and check if you put too much paste on the cpu because that would affect how effective your cooling is between the two surfaces.
 
I own a Prescott 3.0GHz and at full load (i'm at load 100% of the time) i'm running about 58C, this is with AS5, ive been reading about the heatsinks available and would be best if you look into a all copper HS with heatpipe technology, i'm going to be looking into one for my system.

These Prescott cpu's i think are some of the hottest running Intel CPU's ever released.

Are your temps with the case open or closed up? My side panel is always off.
 
my case air flow is pretty bad.. no intake just exhuast from psu, side and back. i am going to get two 80mm fans for the front for intake. also im running a 6800gt which have increased the temp of my cpu by about 5-6C since ive had the card.
 
has intel ever explained why prescotts run so much hotter than northwoods? i know there have been a few insturction set additions to the core, but i thought that since they shrunk the die, it would run cooler and at a lower voltage, thus helping to reduce temps.... :confused:

Well they added more pipes to get it to go faster (past 3.4ghz), and doubled the cache to help the "to many pipes problem". All this doubled the amount of transistors....so yes they shrunk the die...but filled it backup and then some. The presscott is disaster.

I had a 3.4E for two weeks, wanted a 3.4C but could not get one. I finally took it back and got a 3.2C. With my Zalman 7000ALCU and AS5 the 3.2C runs idle at 31C load 47C. The 3.4E was idle at 45C load 64C. Roughly 14C cooler across the board......not to mention about 20-25watts less of a power drain.

I wish they had a desktop Pentium M motherboard with a better chip set!!!
 
they did not add more pipelines, they extended the existing pipe to 36 stages.

the prescott runs so freakin hot because when they shrunk the die, they also decresed surface area of the core. so while it is taking less voltage and should be giving off less heat, since the core is now makin contact with even less area than NW was, its heat wattage rating is higher.

what do you have against the 855GE? in any case, centrino2 is coming out soon with a new chipset.. however DFI has a s479 board for p-M that was overclocked to 2.8ghz and raping the entire competition, its got 1mb of cache and 200mhz on the fx-55 at taht speed :eek:

wow mang that's hot.
I'm running water and @ stock freq, I'm running 32C idle probably 40under load. or approx 5C above air temp@ idle. (it's been really cold lately).

When overclocked 250FSB, I can not for the life of me get this 3.2E over 50C.
*************
If you don't want to get wet, I suggest you go with a ThermalRight heatpipe HSK, and a 92mm (if it fits) fan. Be sure to put a potentiometer on that thing, it runs into the 60db-audio range. :eek:

my buddy just picked up the SLK-94 and the 9.2cm tornado and it dropped his OCed temps by 10C (that's 18 Farenheit) !

Its got limitations, like 400FS single channel DDR, and AGP 4X. I know the new one is moving to dual channel DDR at 533..........but lets talk about 800FSB and PCIE. The CPU is great at a whopping 27watts for the 2.1ghz version.
 
Check and see what your BIOS shows the CPU Temps at, It's been my experence that MBM5 or whatever you run in windows is not very accurate. Prescotts will throtle back at 70c, and I had noticed a great reduction in performance when this happens. Do you notice a reduction in perfomance? If not I would guess that your MB is giving you bad information.

Good Lord, those are some bad temps!
But other than what was suggested, I can't think of anything else to change... but you're best bet is to definately change CPU cooling.
 
I had a Prescott 2.4B that ran at 53c at idle and over 70c running prime95 on a ECS Mobo that *supported* the Prescott core. the board revision was 1.0. I originally thought that the temps were just of but after removing the heat sink, the Arctic Aluminum I had used was a little burned. I moved the processor in a revision 2.0 board and it ran at 37c and 45 running Prime95. Just relating my experience....
