Best possible watercooling loop with 3 rads?

post #1 of 9
Thread Starter 
Hey!

Iv'e got a D5 pump/res combo, cpublock, two gpu blocks, a 280mm rad, 240mm rad and a 360 mm rad, in that spesific order. Is this the best way to do it? Iv'e also got a extra EK pump, not mounted.

Any ideas? My temps are a little high. About 85 c on hottest core after 15min og Aida stress test. 4,5ghz at 1.350v.

My rig is in my sig.

Cheers! smile.gif

your 2 gpus at idle only put out about 100W or less (while stressing cpu with aida64), and 100W gpus only heats water 0.25C, so changing order can't help your cpu temps anymore than 0.25C, i.e. not at all.

With that much rads, your delta air to water is only going to be a couple of C while just stressing cpu. So only way you will improve temps, won't involve rads. Only real way to get temps better would be lower ambient, or better water block or better tim but those will all be small gains, aside from large drops in ambient temps.

Okey. It worries med that maybe the d5 pump alone isnt strong enough. Maybe i should try to change the thermal past once more. Its 15 c between hottest and coldest core.

yeah I would remount again to make sure that isn't an issue, but 10-12C is typical spread in core temps for those cpus.

adding a second pump might improve your temps 0.5 to 1C, but not much. Rads have very little restriction.

Okey. Thank you so much. thumb.gif

If I recall Aida is really nasty about driving up temps and 4.5 is a pretty solid overclock I think on those.

I tried to put it down a litte. These temps are HIGH! After 5min.

See if you can weasel down the voltage a bit at that clock speed. Save yourself a few degrees that way probably.

I put on some new thermal paste. I rubbed it on the cpu, and now with 0,2v more at 4.5, almost 10 degrees c less.
