Need advice for Best Radiator for Ati 6990

I believe the AC can go as below as 16 degrees Celsius but I'm not sure if the AC temperature could be equivalent to the room temperature.

Maybe buying an industrial AC and placing the setup close to it will surely decrease the temps.

But since the thread is all about radiator for 6990 I can't advise coz I'm no LCS expert or owner.

whew iam learning while reading...i have seen jojos rig working on brute force no ac 32 at full load dual loop...the heatkiller is really amazing...

32C with no AC? kabugnaw gud... what video cards and blocks?

[EarlZ]

I kinda find 32c a little to low w/o AC, basically his card loads at about 4-6c above ambient.. Im not saying your wrong but even quad heatkillers will delta 10-15c above ambient.

sorry miss read the tread..jojo is using 5970.

Maski 5970, 4-6c above ambient is kinda too low.

Any radiator with copper louvered fins will be great - for me it doesn't matter if thick or thin rad (but I prefer the thin rad to have options for "fan sandwich"- its doable on a thick rad but its gonna look like a monster

For brute force set up, since both the procie and GPU temps are at stake, individual loops is strongly suggested plus the aircon

P0w3rM0v3's rad "fan sandwich" was very ideal

It is ideal that the "out" loop should be near the rad.

maybe at start up?

Yes that was too low... nice kung ingon man gani ana pirmi ang temperature, wala gyud kurat to run 24/7 bisan mag overclock pa to the max =)

At start up sure, but he said load temps i think or i could be mistaken.

For brute force set up, since both the procie and GPU temps are at stake, individual loops is strongly suggested plus the aircon

Theres barely any CPU usage with 4 GPU bruteforcing, not sure with 6 or 12. an i3 dualcore will can even provide the same bruteforcing performance compared to a 5.2Ghz i7. But I guess this depends on the brute force app used if its fully GPU or CPU+GPU.

@ sir noy - here is a good review on rads - enjoy Swiftech MCR220 Radiator Review

@ EarlZ, I jaw dropped when I saw this brute forcing using both CPU+GPU - I really thought it would only CPU does the works

Any sample shots of a thin rad and a thick rad??
