HX-CU1020V recommended fans?

Postby Thaitje » Sun May 13, 2012 8:02 am

I wanna buy the HX-CU1020V 360mm radiator.
But i'm curious about the fan speed.
Because it has 30FPI so it is for high speed fans.

But i have here 3 Noiseblocker BlackSilentpro PL2 that i wanna use, but the rpm is 1400.
Will it suffer performance because it is medium speed.

I read that the best performance is about 1700rpm or higher.
But i find it kinda loud, and i like silent performance.

I consider about this HX-CU1020V or the Swiftech MCR320 Quit Power.
So my question, will it perform with my NB Blacksilent PL2 on 1400rpm good?

Thanks

you need to be producing a high static pressure with this radiator to get the full performance of 1000 watts out of it. I'm thinking about getting 6 of these and mounting them in push/pull on the rad.

I'm not sure if static preasure multiplies when stacking fans in this manner. One review hinted that it does.

A review on our radiator mentioned that we needed at LEAST 3 fans that each produced a static preassure of 6.0 mm-H2O to get around 800-900 watts of cooling from the radiator

Google search: static preassure needed for HX-CU1020V. Alotta good stuff out there. but from what i've seen out of 100's of fans, koolance fans will do the job right.

Hello Thaitje,

If you're concerned about noise, I'd recommend a lower FPI radiator. With a lower FPI radiator, you can run fans with lower RPM. You're right, a high speed fan would definitely be more noisy. Though, you could always get a high speed fan, and throttle it down. If you keep your eye on the temperatures, you should be able to find a temperature you're comfortable with, with a fan speed that isn't too loud for you.

To answer your question, a 1400RPM fan could work with decent temperatures. The performance wouldn't be as good as a higher RPM fan. It really depends on the heat load too. If it's only a CPU, and you're using a 3-fan radiator, those low RPM fans will have no problem. On the other hand, if you were stacking a CPU, four GPUs, RAM, Hard drive, etc. on a 3-fan radiator, you may have a problem. :)

Thanks,
James B.

I have a dual 120mm radiator and I tried using four fans two pulling and two pushing which worked and I then went to four pulling and got better results.

I used a spare 120 mm fan with its power wires connected to a DC voltmeter with the fan on top of the running fans. Temps shown are with room temperature more than likely about 80F and fans at full voltage.

Here's my results.

Fan on top and bottom
1.97 Vdc
Coolant temp 95F

Fans on top
2.04 Vdc
Coolant temp 93F

As shown stacking the fans on top of each other produces more airflow.
