Silver Arrow - Fans needed?

post #1 of 5
Thread Starter 
I have a silver arrow CPU cooler and I was wondering if I really need the CPU fans that came with it? I noticed some people have mixed opinions on this and thought I would see what you guys suggest.

With decent case fans and good airflow (which I'm guessing you have) it's really good without fans.

Most people notice no change in temperature when using one fan, and only slight increases in idle/load temps with good air flow.

If you're serious about getting the most out of the chip, though, I recommend leaving them on.

Thanks, I am moving my case onto my desk as I get my new mobo on Tuesday and my cats hair gets trapped inside the dust filters when its on the floor, so I was wanting to reduce the noise from the CPU fans with it being next to my head when I game.

The only certain thing is your actually trying the fanless Silver Arrow out and see if it works and whether or not you accept the thermal outcome.

Other than this ultimate confirmation, here is my feedback:-
1) Your case is HAF-X which is a fairly good airflow case, assuming you have set it up right with well defined air intake and air exhaust paths

2) Your two GTX580s have traditional cooling design which exhausts most heat out of the case, meaning the case interior will not be affected much by this. This provides a good environment for a fanless CPU cooler.

3) With the above 2 'pros', I think it is quite feasible to go fanless for your Silver Arrow, provided that you do not highly overclock your i7-2500K.

I suspect a slight or even moderate overclocking is do-able. I base this prediction on 2 observations:-
a) the Silver Arrow is in the same category of the NH-D14

b) a fanless NH-D14 can handle a 4GHz 6-core i7-980X in an Antec 1200 case with the side panel opened

4) IIRC, member calvinbui runs an i7-2600K with a fanless Silver Arrow as well. So, perhaps you can PM him and ask for his experience.

5) One 'cons' of this fanless setup is:- with a slightly overclocked i7-2500K, it could potentially become a bottleneck for your GTX580 SLI at the 1920x1080 resolution. Perhaps a moderately overclocked 2500K is enough. You might also ask calvinbui on this aspect as well because he is also running GTX580 SLI at 1920x1200.
