i7 + 6970 Rad Size

post #1 of 6
Thread Starter 
I currently have RX360 cooling my I7 2600k and want to put the 6970 under water without significantly raising the temps. How much more radiator do I need to add?

Is this http://www.swiftech.com/komodo-hd6900.aspx one of the better blocks for the SAPPHIRE 100311-2SR Radeon HD 6970

Thanks again

That should be a good one, just make sure you select the right one depending on which PCB design your card has.

I would say try it with just the RX360, if you're not happy add whatever size you can fit in your case, and meets your budget.

you should only need another RX 240 included in the loop and temps shouldn't really change. for most standard setups my rule is 240 per core in loop.

A thick radiator like the RX360 should be more than enough if you run your fans at a decent speed. Also, the Sandy Bridge i7 doesn't produce a lot of heat so you should be perfectly fine.

@ Finky: Are you saying he needs a RX360 and a RX240 for a cpu and one gpu? That would be what he need for CF 6970 + i7 2600k.

If you do get the wrong version, they do have an adapter. Mr. Sakamoto used one of these, and initially had the wrong vram block setup. Here's his post on it. You may want to ask him how his temps are, he's using a 2500k @ 5.0ghz + hd6970 with that block on a GTX420. If his temps are where you want to be, you may be able to get away with a RX120 if you want to save space, but I say try it without adding a rad first, just to make sure you actually need to.

You should be fine on the RX360 depending on what fans you are running. I would stick with that for now and see how it goes, you can always add more later if you need / want to.

It also depends on what you are doing with your rig, for gaming you can easily get away with a 360 (I used to run my rig with 2x 120s), for folding you might want a bit more rad space.

I am currently running an i7-860 @ 3.8GHz 1.35V and a HD5850 @ 900 / 1100 (comparable but slightly lower TDP) on a MCR220 (w/ 2x GT AP-15s) and a RX120 (w/ 1x 1000RPM generic case fan). I get temps of 60°C and 40°C on my CPU and GPU respectively whilst running BOINC (folding).

Upgrading to 2x MCR220 with 2x GT 1850s and 2x GT 2150s plus the RX120 w/ generic case fan soon, but only because I want to.
