118watt peltier good enough to cool oced xp?

[mikyseee]

I was wondering if a 118watt peltier with water cooling will be able to keep an overclocked XP cool.

At stock voltage and speed it might mannage but you will need a 172 or 220 to do some serious overclocking. The main concern is finding a power source for the pelt and combating condensation with closed cell foam and dialectric grease.

I assume that you are already water cooling. After a year of water cooling I am beginning to look at pelt cooling. If you do not know whether or not a 118w pelt will cool an xp then maybe you ought to do a little more research. You surely do not want to just jump in and ruin your system.

I've been water cooling witha peltier on a P3 and a Celeron for about a year now and they are both still alive. I know all about the precautions with using a peltier, I just don't know how much heat an XP puts out. I currently power the peltier with a seperate 250watt psu and a 300watt psu for the system.

OK, now I know that Donny Paycheck used a 85w on an xp1600 air cooled. The question would be what xp would you like to do this to? My personal opinion is I would not go lower than 156w however it kind of depends on the xp chip your doing it to, level of oc your wanting to do and available funds. That last one is always the one that gets me.

What you need to do is download Radiate II and figure out how many watts of heat your cpu will be puting out. Then dubble that and that's the size pelt to get. Radiate II is here for download on O/C.com just do a search for it. It's easy to use and gives you the options to change voltages and speeds for your chip to see how wattage is effected by the changes you make. Should help you a lot in looking for the right pelt.

ahh. I just looked and Radiate II dosn't have an option for the Athlon XP yet. It dosn't have the new Tulatin chips either :( I'm doing the same as you...hunting for the right pelt. Right now i'm thinking that a 120w pelt might do it. A 172w pelt definately will.

The closest I could get for you was an Athlon Thunderbird @1500mhz and 1.77v radiate says 80w of heat

now I have no clue how close those numbers are to being true for our two chips that we are running...But i'm sure the chips we have are puting out a good amnount of heat. The safe way would be to get the 172w But a 120w may do the job..I don't know. I'm not sure how to figure out heat watts by hand or i'd be whiping out the good ol' calculator and crunching numbers.

I really don't know and it's not worth frying your chip trying to find out....Until i'm positive on an answer I would hold back and keep researching.

Don't know how close it is but I have generally been trying to figure it on an athlon minus about 10w. The tricky part is that the pelt will take the power requirement and lower it resulting in a substantial decrease in watts put out.
