New build hot CPU

[JugHead McGraw]

Just built a new system (p4C800-E w/Intel 3.2E Ghz processor).

When playing quake or Wolfenstein the CPU routinely heats up to 56 or 58
degrees C. In thew bios I have it set at a mild 5% overclock, giving me
3.36Ghz.

My CPU in my last system (p4T533-C w/Intel 2.2Ghz) never got over 47 degrees
C.

Any ideas why the new CPU is so much hotter?

My power fan is registering only 1288 RPM in both BIOS and Probe. Doesn't
that seem a little low? I'm using the standard one that came with the intel
boxed CPU.

Because its running faster?!?

And because the fan is a maybe running a bit slow?? That could be a fair
bit faster for the standard Intel fan.

Have a look in the bios to see if you have the Q-fan control on.

Prescott CPU's run hotter. They are famous for it.

What is the ambient temp?

You may wish to check that any settings in bios for throttling the fan by
temp are turned off so that the fan will run flat out.

Check what happens to the temp when you take the side cover off your PC
case - if the temp drops significantly then either increase case
ventilation, clear the internals out using rounded cables, remove
obstructions, remove excess internal peripherals, consider a case with a
vent straight over the CPU (some of the best temp readings occur with this
simple mod).

The latest "E" suffixed processors, also known as Prescott, are
known to run a lot hotter, the older Northwood processors.

The newer Prescott core w/ 1meg L2 cache, runs hotter then the older
Northwood core with 512k L2 cache - even at stock speeds.

It's because your new CPU is better and faster then the old one.

No, it isn't. Prescott is about the same speed as the older
Northwood, but consumes 21 more Watts for the same job!
Prescott consumes normally about 103 Watts! Sometimes a lot more.

Lol..
Yea.. I am wondering if this will be the next IntelMyth to come out
DOWN with MHZ and IN with total POWER CONSUMPTION hehe..

"the new range of p4 processors use well over 118 watts, compare this to
amd's high end chips using only 86 watts.. The choice here is simple, why
use something that's substandard"
woot
