MCR320-QP Fan question

[soulesschild]

I have a used MCR-320QP that I got used and it came with 3 yate loon medium speeds. I'm looking to ramp up the performance a little bit since I need to get 3 new fans for my ATCS 840 anyway and was thinking of just swapping out the fans on the rad for some Scythe S-Flexes (or other recommendations, I just have used a few Scythe S-Flexes and have always liked them), but I think before I read that S-Flexes aren't that great on rads. True or false?

I was going to mount 2 yates in the HDD bay fan area, and 1 in the ATCS PCI cowl. But if people think the yates are the best I can get on the MCR320-QP, then I'll just mount the scythes in previous said locations :)

Try 6 70cfm yates.

I haven't considered push-pull but I might try it. What if I wanted to keep them single fans? I'm just unsure of how I would mount the rad using push/pull due to the way CM has us mount the top rad.

If you have enough room, try 38mm 60-75cfm fans.

I've tried every combo with the mcr320, but you will get 2-3c better temp with 6 fans. If I could only go with 3, I'd use the 38mm fans.

I have S Flex on my MCR320 and I think they are working just fine.

I have Yate Loon D12-SH's (High Speed) with a fan controller on a MCR-320, and they work great at 7-12 volts, albeit they are a little loud at full speed. That being said, I also have 2 Scythe SF-21F's at full speed on a MCR-220. If I were to purchase new fans, I would more than likely purchase the Scythes for my MCR-320 rather than the Yates, due to the fact that I can run them at full speed and still have quiet.
