Bonnie HC vs MRC220

post #1 of 6
Thread Starter 
Just wanted to give a heads up. I ran a Bonneville HC from xoxide for a year or so, and was happy with the cooling. Upper 20's and Low 30's at 100% and my GPU at 49-53°C. (100%). I developed a leak, and replaced it with a swiftech MRC220. I am very surprised, but I'm getting a pretty good drop in temps. I'm now 25-26°C and my GPU never goes over 43°C 100%. All things are equal here. Ambients are equal, and fans are the same. I read that the MRC220 is designed for low rpm fans, but I am running 4 high(97-100) cfm fans. 2 pulling and 2 pushing.

Yes, higher fans are definitely better for any rad but I find that the swifty ones really perform much better with the thicker/higher CFM fans.

Hmmm I would have thought that the Bonnie HC would have been better than the MCR220? Better Flow and heat dissipation.

Thanks for posting your results!

Now if We could just get Martinm210 to do the RAD testing.... I know he had a 77 Bonnie on his list to do!
(Just teasing ya Martinm210 if your reading)

Glad its working out well for you...Long time no see......That surprises me to, the 220 I had just didn't do any better then my BIP 240...They did OK but my 240 BIX did better...I just had them on a 3800 Venice on it then to, so really almost any 240 rad was over kill anyway with high cfm fans like i was using...

Since its doing so well for you I might have to get a 320 and give it another shot, load it up more..

Yeah, that suprises me a bit too, but I will try an confirm that with my own. I always have a nasty habit of getting board with one area of testing, so I pulled away from the rads for a bit to do some CPU testing.

Time to get back to it as soon as I finish some new pump top testing..
