H50 fan use question.

Dreadhead · 21 Jun 2010 at 00:24

I am just playing around with a Corsair H50, taking temp readings with different fan speeds before I begin to overclock.

I have an additional fan I can add to the fray and I am thinking of setting it up in a push/pull fashion.

The 2 fans available to me are:

Noctua NF-P12 -54.32CFM with a static pressure of 1.68 mm H2O
Akasa AK174CB-4BLB -59.05CFM with a static pressure of 3.57mm H20

What are peoples thoughts on mixing the differently specced fans. would I be better putting the higher static pressure fan pushing air into the radiator and the lower Noctua pulling air out, or vice-verca?

Also would using the Noctua impact performance over say another fan at equal static pressure to the Akasa?

Cheers

i highly doubt that you will see temp. benefits from using 2 different fans... in fact i expect them to be worse.

I've got a H50 setup in push/pull using identical Sharkoon Eagle 1000 fans (1000rpm - 36.8CFM - 19dB).

Currently testing my sytem @ stock and under 100 load my temps are 60c
Tested @ 3.8Ghz my load temps were 70c

I've got some extra screws if you send an email via my Trust account.

Well I will test it out then. Consensus elsewhere seems to be that you should use a more powerful fan to push as the resistance of the rad will reduce the amount of air that needs to be pulled away.

@Zico thanks for the offer buddy, I will email.

System specs else data is useless?

I added an apache fan to pull to my setup (akasa viper fan pushing air) and it only dropped temps by about 5C. Didnt think it was worth it for the increased noise level.

Is there a way to split the cpu 4-pin header connection so that it is able to control 2 fans rather than just one? If I could do that, then it would be quiet at idle and a bit noisier on load which would then be worth it.

Pretty sure that you cannot split the header, but Zalman do some cheap fan controllers that should do the job.

I7 920 @ 3.8Ghz @ full load under Prime 95 (1.21v cpu) 71 across all cores via Core Temp.

System house in a Silverstone Raven R02 with the three 180mm fans set to high and only the two sharkoon fans as push/pull on the H50.

Crossfire 5850's currently @ stock.
