My System Specs

Default Optimal water setup

Hello all.

Have myself a semi custom watercooling unit here and would like to know optimal setup for it.

System Specs:
Phenom 955 @ 3.6ghz
Gigabyte MA790XT-UD4P
2 x 2gb Gskill ripjaws ddr3 1600
XFX Radeon 5870
Swiftec MCR220 + 2 x 120mm lian li fans
Thermaltake pump (500lph) + resevoir
Swiftec Apogee GT block
3/8" tubing across the board
Huge ass CM stacker on wheels for a case
Corsair HX750 watt psu

The rad is mounted in the front with the fans pushing air into the case sucking air from outside. The fittings are top mounted, Also have a 120mm yate loon blowing across the hdd cage with a 120mm yate loon for exhaust and top mounting 80mm for exhaust as well.

So far after an hour of OCCT the chip doesnt go over 52* and idles about 30. Is that about as good as im going to get with that setup?
Any input is greatly appreciated.

As far as I am aware it doesn't really matter as the loop usually equalizes the
temp. Most people who do go for "optiaml" set up go Res > Rad > CPU > Chip set(s) > GPU > Res.

However I am not an expert on water cooling and am just going by what I was tol.

Good luck.

Amuse Me is correct in his loop order, in that it helps the coolant temp the most if it's in that order. If you're looking for lower temps, more rad area is the key, and a newer gen block like the Apogee GTZ or XT would help as well.

He is correct, except his loop would have trouble. he forgot the pump! Res > Pump > Rad > CPU > Chipset(s) > GPU > Res

You might be able to gain a degree or two with a stronger pump - those Thermaltake things are weaker than the 500lph would suggest, and if you're pushing through multiple blocks, I wouldn't be surprised if your flow rate had dropped below ideal. And yeah, probably a few degrees to be gained with a better waterblock. On the other hand, it's not like your temps are in any way critical.

I'm getting 3c down if I push fans from ~1500rpm to ~3000rpm in similar set up. See sig Antec 902.

After looking around i did realize my pump is crapola. So im looking at a really nice swiftec 1200lph pump and changing the loop to 1/2" with 7/16 tubing.Also getting a swiftec microres. The resevoir size really doesnt matter id imagine, it would just mean more filling. Would also like a heatkiller 3.0 but i dont have a credit card to order one amd platform from the states. Im currently running res -> pump -> block --> rad -> res

Wow, i would have thought the GPU's would be higher on the list as they can have some crazy temps? i cheated, i went with 2 rads and it works superb. Mine is Microres/Pump/GPU x2/South Bridge/Rad 1(240 4 fans)/CPU/Northbridge/Rad 2(240 3 fans)/Microres. I couldnt decide on the order so the two rads meant i had rads right before the two things i wanted to cool the most, the GPU's and the CPU. other benefit, is that 2x 240 rads was much easier for me to mount than say 1x 320 rad or something. Now if i can get the mobo fixed, ill finally be able to lock down the damn side door on the case and leave it alone
