2x120 Radiator enough for CPU & GPU?

Howdy all. I got a swinging deal on a Swiftech MCR220-DRIVE-B 2x120 Radiator and a brand spanking new 4 pin MCP350 pump for it. Rad specs here:Swiftech MCR220-DRIVE-B 2x120 Radiator w/ Integrated Pump Housing & Reservoir. I'm getting an XSPC RayStorm CPU water block to replace the Corsair H70 and considering getting a EK full coverage block for my 7970 as well. I don't do massive overclocking. My 2500k is at 4.6Ghz@1.3v and my 7970 runs 1125/1575@stock volts. With 4 Scythe Gentle Typhoon AP-15 1850rpm fans push/pull on the rad will this setup keep the CPU and GPU at moderate temps? Say 70c area with load? I know 70c is hardly optimal but it's far from dangerous and both my CPU and GPU are already running 100% stable under load at their current speeds in that temp range. I'd just like to do something about the 7970 fan noise and as long as I'm tossing in a new water loop I would not mind tapping in to it to keep the GPU cool and quiet as well. About the most demanding thing I do is game (BF3 mostly) and usually neither the CPU or GPU are at 100% at the same time if ever.

Whatcha think?

You'll get moderate temps. Not close to what you "could" get with water, but your estimation of of "moderate/slightly better than air temps while becoming quieter than the GPU fan" are accurate. I can't give you a more accurate estimate because I'm not sure of your ambients.

Exactly what I'm hoping for. I've done the extreme water loops before. I've done water with pelts. I've done phase change. I've mixed phase change and water loops. I don't want the overhead any more. I'd like a nice clean low maintenance setup that's quiet and simply keeps my gear from getting hot. Based on my experience I think the setup I outlined would achieve those goals. My "guesstimation" would put the setup's abilities at about 45c over ambient under heavy load on both GPU and CPU, which is exactly where my target is. I'm just looking for affirmative nods from a few other experienced enthusiasts before I pull the trigger on the blocks and fittings.

Assuming a 22C ambient, I'm going to guess 33C over ambient on the GPU and 38C over ambient on the CPU. Whoever's closest wins the cookie jar ;)

Ur on... but we're going to have to wait a lil bit. I installed the pump in the rad today and set up a small loop with a spare reservoir I had laying around. Pump moved a lot of water but was noisy as hell. The 4 pin connector was damaged in shipping and I had just replaced it. Whatever smashed the connector looks to have damaged the pump as well. I'm going to have to exchange it. Probably won't have the replacement for a few weeks. :(
 
Please update us when you can, I plan on doing the same thing once my 3930k and 7970 arrives. Only difference is that I will have a 120 and a 220.

Good luck and thanks!

Will do. Pump is getting dropped at the post today. If I cannot keep the temps in a moderate range I'll be adding an additional 120 as well. Those 3930's put off a lot more heat than my 2500k, but my lil project should give you some indication of where the performance will be.

I also have an old MCP600 pump in perfect working order that I might press back into service. It's still silent even though it runs at full speed only. Thing generates a good amount of head pressure so having a 120 and 220 in the loop won't be an issue.
 
I might go with a 280 instead of a 220, I just need to look up more threads to see if the 280 will fit fine at the top of a 650d. Like you, I am going to overclock just the cpu or just keep it stock since I like the quietness of low speed fans.
