Hi, I've always had issues with my CPU running a bit hot compared to what I've read in other forums online. My CPU idles at 47 C and gets up to 70 C during game play sometimes (or just sitting at the opening menu of Prey after a few minutes). Really I have two questions some of you may be able to help me with (I will post spec. details below them): 1. Will upgrading my video card release stress from the CPU and not let it get as hot when gaming? 2. Why is it that my CPU runs so hot compared to other peoples reports? I made sure that their configuration was the same as mine (no overclocking, aftermarket cooling apparatus, etc.). Some of their reported temps are between 10 - 18 C less than mine at idle. Here are my current specs: Intel Pentium 4 3.0GHZ (w/ supplied heat sink & fan) 1 GB DDR400 Asus P4P800-E deluxe board GeForce FX 5200 (128 MB) **XFX GeForce 6800XT -- Upgrading to I don't have anything generating too much heat inside, have 3 case fans, HD and CPU fan. My motherboard stays around 39 C at idle so I assume that the internal case temperature is OK if thats not getting too hot as well. Any ideas/suggestions greatly appreciated!

Well, here are my answers....

1) If anything, the new video card would make your new run hotter, because the 5200 runs cooler than the more powerful 6600. The video card won't release much stress (if any) from the CPU.

2) The only thing that I can say here, it to make sure that nothing is obstructing the airway to the CPU. All it could take would be a stray power dongle sitting on top of the processor, and it could get pretty warm.

Also, tell us what power supply unit you have, and how many watts it provides, as the 6600 has a higher PSU reqirement than the 5200 does.

What size are your fans and how are they positioned in your case? (intake or exhaust? Side? Top?)

Is this a large or fairly small case?

2. Why is it that my CPU runs so hot compared to other peoples reports? I made sure that their configuration was the same as mine (no overclocking, aftermarket cooling apparatus, etc.). Some of their reported temps are between 10 - 18 C less than mine at idle.

It is most likely due to the fact that there cases probably have superiour airflow with larger, more powerfull fans.

Like marvinmatthew says, adding the 6800XT will do nothing but generate more heat, since it runs alot faster than your FX 5200 does. Actually, a FX 5200 should not make that much heat at all.

Thanks for your answers guys. It's a Lead-Power 550W PSU.

As for the case & fans. It's what I would call a standard sized atx case (four 5.25" and two 3.5" below those.) There is a 92mm case fan in the inside - lower front of the case (came with case) for intake, along with 5.25" bay HDD fan array bringing in air too (obviously some of it getting warmer after passing by the HD).

On the back there are two smaller fans attached to the backside of the case blowing out air.

I did read on intel's website that some pentium 4 processors are supposed to be used in cases that are deemed "Thermally Advantaged Chassis" (http://www.intel.com/support/processors/pentium4/sb/CS-012526.htm) that have a duct in the side of the case for cpu air flow -- I do not have this. I was considering making this duct..you guys think it would be worth it?

By Me.Temperatures vary from different CPU's.

It all comes down to reasons such as your CPU make, model, core design, frequency, cooling. Position of PC, position of other hardware around the CPU. Ambient room temps, Location, etc.

Mine runs at 29 Degrees Centigrade on Idle.

^ Here is a little insight.

My applogies, I thought I read that it was a 6600, not a 6800. But it makes little difference.

Adding the opening on the side of your computer would be a good idea.

-Or-

You can do what I did when I first over clocked my P4, take off the side pannel, and put a regular plug-into-the-wall outlet facing towards the innerds of your computer. That might help (although it would look like hell).

Kommandant Ro╬▓:

I made sure they had the same CPU as I did (Northwood core) w/ no overclocking, and from what I saw they just had standard cooling setups.

marvinmatthew:

I've actually thought of doing your idea (#2) before :lol: I think I might try a new heatsink/fan setup. What do you use?

try runing your computer with the side off and a box or portable fan bowing air in, if this helps your cooling issue, the problem will be the case cooling, consider adding more cooling fans or a diferent case with better airflow

I put one of those indoor/outdoor thermometers in the case and the reading is pretty low @ 32 C --- methinks maybe i need to try a new heatsink or thermal grease?

Yay! I think I found the root of the problem -- I removed my CPU/heatsink/fan and found a thick layer of dust/crud caked on the top of the heatsink so no air was getting down the fins. Unfortunately the damn Thermal glue stuff Intel includes on their heatsink glued the CPU to it and when I pulled on the heatsink it yanked the CPU out of the socket without lifting the arm (it was beneath the heatsink so there was no way to get to it) No harm was done fortunately...system still turns on...just need to grab some new thermal spread stuff. I'll post my new temperature after I get it back up and running on Sunday.
