L20 Pump with 9800GX2 ???

[Ruszek83]

:yumyum:I have a Question:

I have an old VERRY OLD Water colling system http://www.dooyoo.co.uk/pc-accessories/asetek-waterchill-cpu-vga-cooling-kit-kt18a-l20-220v/lying in my basement, it is old Asetek with L20 pump and 1x120mm radiator i was wondering if i can use it to cool my 9800GX2 with "aquagraFX for 9800 GX2 G1/4" waterblock.

I don't have cash for a decent pump and radiator so it is all i have.

BTW, i want to use it ONLY for my graphic card since it is topping at

89Celcius....

Ok the L20 isn't the most reliable appparently so you may need a new one because you haven't used it. If its good to go then you should be fine as it shifts 700LPM.

If you had said 9800GTX I'd have said put a high speed fan on the radiator and be done with it but you didn't. If fear the 9800GX2 may need 2x 120 radiators or 1x 240 radiators or 1x 120 dual row radiator given its heat output.

I have 2x 8800GTX in SLi and they hit 70-80C (weather dependent) at idle and go much higher during use. Their thermal cutout is 110C so they are built for these temperatures. However once hooked up to a PA120.3 with my CPU everything sits around 60C at load. The PA120.3 is a double row 360mm behemoth of a radiator so thats the cooling power you need.

Is it the radiator that came with the kit? Or is it a Black Ice Pro like almost everyone upgraded to back then?

I have no idea but this the one that was in the kit thick 1x120mm and it came with a verry loud 2inch fan... i think could buy new "low speed" radiator and i guess the 240mm should be just fine, or am i wrong ??? ;-)

I would think you would need 240mm of cooling. How you get this is your choice. Dual row radiator (PA120.1), two single row 120mm radiators (XFS 120) or single 240mm radiator (XFS 240) would all suit your setup. I'd go for the biggest one I could personally. PA series are the daddy and PA120.2 would keep that thing chilly easily with low noise fans.

So 240mm radiator and my L20 pump should be enough? i hope so ;-)
