Hi,

Having rebuilt my rig over the last week i have a few questions re the water cooling setup.

Have got my 9850 and 4850 in one loop, both with D-Tek Fuzion 2 blocks on them. It is currently set up Pump - Rad - CPU - GPU - Pump.

Is this a good setup and what temps should i be seeing with both in the same loop?

Regards

Have you clocked the cpu, and/or the gpu, and what temps are you getting, idle and load?

I've heard if you have too much in one loop your water will eventually warm up and provide no cooling at all.. I dont have watercooling though so I wouldnt know tbh.

I L0L'd at that :D I wouldn't know tbh... ;)

I'd try it all in one loop, and if that's not working out then add in another rad, testing testing testing ;)
 
With the exception of always having the res before the pump, it doesnt matter what order the blocks go. I have Res->Pump->Rad->CPU->NB->GFX->Rad but adding the second Rad to the loop made little difference to the temps.
 
res-pump-rad-cpu-gfx-res (single loop)

that's my order and works a treat. already passed my highest air overclock by 200mhz with new water cooling and more to go! temps are fine.

what size res's have you got? and which is the first-second?

you'd be pretty miffed adding that second res for it to do nothing, no?

I take it you mean Rad (not Res), ive got 2 x 120.2. I added another in the roof and to be honest, at idle i can have both sets of fans on the two Rads not even spinning with temps at 30ishC (8800gtx very OCed/1.7V on the NB and 1.6V on the CPU) but max temps when all components are stressed are no lower than when i had just the 1 Rad.
2 seperate loops, now thats a different subject. My GTX never goes above 50C and my E6300 at 3.4 never went over 65C and that was during the (2007) summer.

Hmm, so 2 loops was a lot cooler then? Might have to invest in another pump..
 
So long as your single radiator is sufficient for your loop, i think two loops or two rads are overkill.

My double rad keeps my oc 4870 at 43c and my 3.8Ghz q6600 at 67C.
 
Sorry to go slightly OT, but I noticed some people said:-

Res > Pump > Rad .... etc

I would have just went:-

Res > Pump > CPU ... etc

Does going through the Rad initially make the water slightly cooler so should in theory give better cooling when it reaches the first point on the loop, i.e. CPU or GPU?

Thanks. :)
