Watt?

Hixup · 06-20-2002, 04:26 PM

How many watts for a amd athleon xp 1900+ (1600mhz). Im on a 280 (i think) power supply and want to over clock the chip about 144 mhz. any ideas how strong of a pletier should i get?

As big as you can get!

Acutally, you would probably need at least a 156W but a 172W or higher would be better. The highest wattage pelt that I have seen available from water cooling vendors was a 220W.

Also if you are going to put even a 156W pelt in your machine, you need to have it powered by its own power supply. Even a 156W pelt @ 12V will draw close to 14-15amps by itself. Most smaller computer powersupplies cant even handle that load without anything else attached to it.

Finally, those pelts will put out A LOT of heat (wonder why?

) so you will need a good water cooling system to handle the load.

im not planing on using water cooling, the old fashioned head sink and phat fan. its probely better but in my mind, water + computer = trouble. i think im gonna get this case but im not too shure. i just dont want water in a computer.

In that case DONT try and pelt coold your CPU!!!!

From what I have heard around the forums here, the maximum pelt you can cool with a Heatsink + Fan combo is an 80W pelt and that pelt is TOO small for an Athlon or an XP. The Xp will put out around 65-75W of heat and an 80W pelt will just cause it to fry.

Unless you have one giant heatsink + fan combo.........like the size of your case

i might be able to get my hands on this new carbon-foam compound. Supposed to be the most uber-L33T heat sink there is. Its a foam kinda like stryofoam, its black and costs like 500 bucks for a piece of it, scraps awalys work though! if i whip out my math skillz i can see though...

Im not too shure on watt... doesnt say but it is 12 volt
