60mm or 45mm tick rad

[blair]

hi i have a 360mm 35mm thick rad at the moments and my OC 1090T and 7970 are getting to points where the fan have to be on high in games to keep it cool. i only use one set of gentle typhoon 1850rpm fans, id like it if they could be ran at 40-50% so they are nearly silent which rad would be better 45mm or 60mm fill be a alpacool full copper, my 1090T gets to about 57C and 7970 60C (BF3) with fans at 50% how much will a thicker rad improve these temps?

Cheers

Well, I'm not sure what you're getting at but to answer your question a 60mm RAD would be the best as it has the most volume for cooling capacity.

However if you're going for silence I would say go for a 60mm thick 360 rad AND something like a 60mm thick 240 rad.

Dont see the point in getting a thinner rad if you have room for a thick one....

The only thing I can think of is that he's worried about the low RPM fans being strong enough to blow through all 60mm

picking the right 60mm rad with the fin per inch (FPI) between 6-12fpi and some mani's are

stretching that 20fpi can use 1200rpm or less.

XSPC - RX360 7FPI

Phoyba - 35223 12fpi

Black ICe EX360 - 20fpi

AlphaCool - UT60 - 10fpi

thats why TTL always opts us to use the thicker units, to save headaches with headroom.

so 1850rpm fans and the alphacool ut60 should be fine even when the fans are ran at a lower speed. I know the thicker the better but i wanted to make sure the fans would be fine with it.

Cheers for the help

You'll be fine. I've been running the old noctua NF-S-1200 @700-1000RPM, in pull on the old Thermochill PA 120.3 for years now. (Most heat i have been putting in, was with a E6600 @ 1,6V, a NF650 chipset and a X1900XT).

Just make sure to use a low FPI rad and use a pull config.

They made a test on Martins Liquid Lab some time ago: http://tinyurl.com/c6jv2nh

In my last case I used a XSPC RX360 rad for the cpu alone with 6x Scythe Kazi Jyuni fans in push/pull at 5v and they kept my 2700K at below 70c per core when benching, and the chip was running at 5.2ghz using 1.525v.

I would say that a decent 60mm rad with some decent fan's on it will easily cope with a cpu and gpu, but if the temps start to get out of hand then you could always just add another rad if you have room and drop potentially 5c at the most I would say off the temp's.

Just make sure that your pump has enough power to push the fluid through the block's and rad though.
