Sufficient cooling capacity?

post #1 of 8
Thread Starter 
I know this seems minimal but I'm trying to keep things internal in a Mid Tower case. I'm thinking an Arc Midi. Do you think that a RX240 would suffice for a 2700k and a 7970/680 or is there another 240 rad that would work better, or a different Mid Tower case that would enable me to have more? I understand I'd normally be suggested more RAD room but what differences am I really looking at? In my mind it's more than an H100 in surface area per device. Or like PNY's 580 with CPU and GPU water block self contain unit only had one 120 RAD at like 50mm thick that cooled the GPU well and CPU under par then why wouldn't a 55mm thick 240 with higher flow do OK?

Having used an Arc Midi and water cooling, as well as water cooling another rig (both dual GPU), I would recommend at least a 240 up top as well as another 120 or 140 in the front or rear. The RX240 will fit without issue, however also look at the EX240. The EX is cheaper and is better performing at greater than about 1200rpm fans. The RX excels at less than 1000 rpm. A 120 or 140 will fit in the front with little or no mods. You can fit a 240 in the front if you drill out 6 rivets to remove the lower HDD cage. Very simple mod, and is exactly what I did in my Budget BOINCer build in my sig.

Bottom line, I would recommend at least 360mm of rad space total, ideally 480mm.

I was going to use NF-F12 in pull for a rad up top, so would that favor the EX over the RX? Even though the RX is much thicker?
post #4 of 8
Yes. If you use those fans at full speed, the EX will perform better. The EX and RX have much different fin design, therefor determining which fan performance works better. The RX is thick, but has wider fin spacing, making low speed fans better. The EX is thin and has a tight fin spacing (double fin actually, they look like >< betwen the channels), making higher RPM and/or higher static pressure fans better for it.

Well the NF-P12 are only 1300 RPM at 12v. Would there be a radiator with more dense fins that is also thicker that would be even better than the EX240? Basically what is the BEST 2x120 rad I can git for one set of NF-F12's in either Push or Pull? I also may be considering COOLER MASTER SickleFlow 120 R4-L2R-20AR-R1 hey have more CFM and the leds I want and aren't any louder.

Some of the Cooler Master fans are iffy. I don't know about the SickleFlow specifically though. The EX rads are about as high density you can get because of their dual-fin design.

U need a triple rad for that. Either a RX with low fans or Ex with medium to high fans

Well now I thinking I'll have better cooling capacity going with a GTX 240 (20FPI) with pressure optimized fans that are still quiet of course.
