I have discovered the one misgiving of a Dual Athlon MP system.. in the nicest part of the year when its too hot for heat and too cool for Air Conditioning.. you get roasted by this towering inferno sitting near you. Had to open the window, turn on the ceiling fan, open the case to keep it comfortable in here. And Im using dual Delta 7000 rpm processor fans and a bunch of case fans... so now now the pleasant wailing of all these nice coolers is complemented by enormous volumes of heat...
Cant wait for it to get over 85 so I can cool down the house! Maybe I should just wear shorts?
BTW its 80 degrees outside... a tad warm for April
Are Intel dual systems this warm? >>
It shouldnt be a big difference. Keeping all other things equal, the dual AMD processors use (at a guess, you didnt give me model numbers) 60W of power each. So, 60+60=120. Keep in mind, you then have to subtract how much an Intel CPU draws. Its been a while since I had a look at P4 power consumption, and I havent looked at Zeon power consumption ever, but at the same clock speed and manufacturing process, the Zeon should be higher, due to a bigger cache. Anyway, IIRC, a 2.0 Willy puts out about 60Watts (remember, Intel CPUs
run cooler, but the power draw is fairly close in between the P4 (at least the Willy; Northwood should be drawing a lot less juice) and the Athlon). Lets assume we are talking about a Zeon on the .13 micron process, so call it 40W (which is a guesstimate, but it should be accurate enough for demonstration purposes). So, really, the difference is 60W+60W-40W-40W=40W. My lamp puts out more heat than that (150 Watt halogen bulb), and it doesnt seem to warm up the room. I'm in a dorm, too, so its not like the room is large, on the contrary, its d@mn small. An average light bulb is 60W. From the rest of your posts in this thread, it sounds like you have quite a large rig (redundant PSUs, for example), so the percent difference of heat output shouldnt be huge going from AMD to Intel CPUs.
On the subject of fans, adding bigger faster fans will heat the room more, not less, though by an admittedly small amount, the amount being the difference in power draw from your original fan to the new one. Your CPU's output a finite amount of heat. A bigger/faster fan will keep the CPUs closer to room temperature, but they do not lower the amount of heat introduced by the CPUs.
