Air Cooling Advice for Node 304

post #1 of 4
Thread Starter 
Hi everyone.

I'm sure there is all sort of fan talk in the Node 304 thread, but I have a plan in mind and looking for some input. First off, my Node 304 build was purposed to be small and powerful, not necessarily quiet. Let's keep in mind that it sits on top of a Dell C1100 in my office, and under the C1100 is a 4U Norco RPC-4224 storage server, and a 2200VA Smart UPS under that. My office isn't loud, but it's not quiet.

Build:
Case: Node 304
CPU: i5-4670
Mobo: Gigabyte GA-H87N-WIFI
RAM: 1 x 8GB Crucial Ballistix Tactical (ULP 1.35V)
Drive: 120GB SSD
PSU: XFX Core Edition PRO550W

All stock case fan and CPU fan. CPU temps hit about 72 max when running Prime95. My current thought is to get a Hyper 212 Evo, and leave the stock fan on it. The fan would be in the front of the cooler, blowing air through the heatsink toward the exhaust fan. I'm thinking about replacing the exhaust fan with BitFenix Spectre Pro 140, which is the most powerful 140mm fan I could find, without breaking 40 dBA.

What I am curious about is the front fans. Does anyone know what the model of them are, and the specs (CFM and dBA)? I'm thinking bgears b-Blaster 80s for the front, which I've got two of in my 4U storage server.

Thanks!

I don't think replacing the stock fans will be necessary if you're only shooting at 72C for a Prime95 number
(of course depends on your ambient), I'd try it out first before getting the aftermarket fans they're easy to replace. With stock fans and a Zalman 9900Max mine were mid 50s, with somewhere in a 25-30 ambient range with stock case fans on low, and it was silent.

Ambient temps are probably 23-25C, but the weird thing is when I turn the fan controller on low, all 3 case fans stop. I just feel like the fans aren't running on high, when the switch is on high.

One of my small ones was lazy about starting up on low, maybe PSU 12V is a bit low. That said I have replaced all my case fans with Noctua PWMs to get rid of the cabling and run fans with mobo and AIO controllers.
