Do you guys ever feel like your P4's with thermal dissipation in excess of 90 watts is like an additional heater? I've aleays felt like my apartment was always warm even when I didn't use furnace for a whole day even during the winter with freezing temps outside. But now summer is approaching and it's going to get hot now, and usually I seem to run to A/C very often even if the temp is only 85-90F outside.

Also the P4's are pretty ineffecient with power compared to pentium M's and AMD processors. I wonder if my crunchers are jacking up my power bill. :-/

You can bet on that!

Yes, that's for sure. It's like having a radiator set on 100W all year around. :)

If you're concerned about the heat of your CPU, now when summer comes, take a look at this: Thermaltake's Big Typhoon.

Oh, I *know* my crunchers are jacking up my power bill. I estimate about $40/month, at least.

My 2.8GHz Prescott is probably the worst offender, although I think it's not so much the heat output from the processor but the power consumption that causes the power supply to dissipate more heat. A very unscientific "measurement" by placing a hand near the power supply and near the processor tells me so. :-)

Even still, we bear the heat for the sake of science!

The new AMD 0.09 micron parts disipate around 30W with full load, the exhaust of my computer is cooler than my hand.

I used the Big Typhoon (link to picture) but the PIV Prescott 3,4GHz is still running hot and burning a lot of energy.

Hey check out this monster cooler weighing at about 1kg! the Zalman CNPS-7700.
http://www.tomshardware.com/cpu/20041213/index.html

here is an image from THG


I was thinking about replacing my stock heat sink with this one, but I'm not sure if it'll fit. I guess I need to make sure to check the measurements... It's about 14cm wide (5.5"), and 6.7cm tall (2.6"). Hmm that's big, I doubt that'll fit my crowded case.

You can check the compatible motherboards at the Zalman's webpage of that cooler which is here.

BTW
1. no need to install the Korean language support.
2. I have the Zalman CNPS7000-Cu, room temp at 27C and CPU temp at 44C crunching S@H/Boinc 24/7, P4 2.4@2.88.

Thank You for the link. i have been considering that cooler for quite some time but did have the size concern. i still am considering liquid cooled though as i live in Atlanta and it gets HOT down here....
nice to know that it will fit my mobo though.

happy crunching

Hi Willy, I have ordered the Big Typhoon now but not installed it yet. What temps are you having now? I talked to a guy in ocforums.com who says he cannot get the CPU above 45 C with this cooler.

Here's a link to the reply from him.

Another good cooler is this one. Arctic Cooling Freeze 4. I have a P4 3.2 and it went from running at about 47C down to 38C under a full load. It will get the heat out of your computer and into your living where it should be.

I live in Savannah where it gets HOT AND HUMID, and I dont know if my CPU will stand the water floating all the time.

When I installed the cooler I went to the BIOS -> Hardware Monitor and had it running idle for a while. Temperature rose to 50C. That's IDLE!

I don't know the load temp because it's running Linux and the mainboard is not supported by LM-sensors. But I still get temperature warnings. Treshold in the BIOS is 70C, so I guess it's hitting 70C on occasion.

I'm under the impression that the Big Typhoon is a bit slow to react on big temp changes (when going from idle to full load on a Prescott).

That's way too much! Maybe this cooler isn't so good for P4 Prescott? Have you checked that the heatsink is mounted directly in center over the CPU core? I've had a couple of experiences before with BAD overheat, when I mounted a heatsink just a few millimeters to one side. Also check that the CPU fan is blowing, not pulling, and that the heatsink base has good contact with the CPU. You should use Arctic Silver III in between. If the heatsink base is rough, you can use 400 and 600 sandpaper (with water!) to polish it first.

I've been een PC technician by occupation for the last 6 years (switched jobs last month), and I have never seen something like Prescott. Not even the good old Thunderbird was this hot. I've seen dozens of Prescotts with idle temps over 50C. Excessive cooling (lots of casefans and a not standard CPU cooler) are required to cool it down. I've seen a 'build by Intel' MCE system with Prescott that also has temperature problems: they can't even cool their own beast.

Yes: the cooler is in the middle of the CPU (mounting doesn't permit otherwise with this cooler, but even if it does, the base is big enough to shift a few mm), fan is blowing and Artic Silver compount is used. Not polished, it is fine as it is. I also upgraded the standard fan of the Typhoon with a higher RPM Pabst fan.

I truly am angry at my past me that decided to go with Intel instead of AMD. What was I thinking.

Well, if they loose the market to AMD, they can always start selling fast water boilers with a P4 as heater element! LOL

It's sad that you're struggling with that kind of problems. You're also providing great stats to the community, so I think you should've had better luck!

However, it's quite a gap between the heatsink base and the rest of the heatsink body. Perhaps one can mount an airduct to one of the case fans and then, via an adapter, try to narrow the airflow to blow right on top of the heatsink base? The tip would be flat and small enough to just cover the area the heatsink base covers - or less. I mean, it should be room for such a device. Maybe one could use a plastic adapter for a vacuum cleaner or garden hose or something? :) I'd like to try this when my Big Typhoon arrives.
