How Much Radiator do you Recommend?

post #1 of 7
Thread Starter 
So right now my i7 950 is being cooled by an XSPC RS240, it does a pretty good job keeping max temps around 60C.

I just purchased an R9 290 and I am looking to add it to my loop. How much more radiator do you think I will need? My original thought was to add a 120mm and call it a day, but I am starting to think that may not be enough. I could also do a 200mm in the front, but the lack of 200mm fans worries me about that option.

So what do you guys think I would need to add the new card to my loop?

Also, if anyone knows how I can squeeze another 240 in my 650D it would probably alleviate these issues haha.

Thanks.

Stock that 290 has an estimated TDP of 250W (100% load) and your 240mm rad with 1400 RPM fans dissipates about 125W. Another 120mm rad will probably be fine as you don't likely run both your CPU and GPU at 100% load.

I would go for at least 360mm total, 480mm if you intend to overclock (which you undoubtedly do). Let me dig up some rad info regarding your case and I will get back to you.

Edit: I would just go ahead and give the single 120mm a shot. If you need more, I would get a 180mm Alphacool NexXxoS XT45 and your choice of fan. You should be able to just mount the radiator to the mesh in the front using some small washers and the included 30mm length screws, without having to drill holes and cut on your case. You only need 4 washers, but I have no idea what size they need to be, so you might have to go pick through the local hardware store. Links to everything else \/

I like the idea of that 180mm that seems like it would more than enough and allow for higher overclocks. Thanks for the advice.

General rule of thumb is always: 240mm base for a CPU only loop, add another 120mm radiator for each major component you put into the loop. If you could use a 3X140mm radiator, I think that'd be optimum for your situation. Not too overkill like a 480 would be, but will provide more performance than a 360 if you have both the CPU and GPU under load.

Otherwise, a 360mm rad with higher RPM fans would perform pretty good as well.

EDIT: Whoops, didn't see the 650D. I guess add the other 240mm radiator, I don't think a single 120mm rad would be worth the investment.

I second an Alphacool radiator. If you can only fit a certain size, at least you can make it thicker and get more cooling performance that way. The XT45 and UT60 are beastly.
post #7 of 7
with 180 watts from the 950 and say 300 from the OC'd 290 ...that's 480 watt

Martins says ya getting about 125 watts outta ya existing rad at 10C , 1400 RPM ...adding a 360 would give ya another 188 for a total of 313 watts at 10C

At 1800 RPM in push/pull, ya get 392 watts which is 83% of the theoretical 10C number so not bad at all
