Right, after some research it seems that if I replace the stock fans on my h70 I can get about 5degs cooler on my 930.

So, I think the best option would be http://www.overclockers.co.uk/showproduct.php?prodid=FG-059-AK&groupid=701&catid=57&subcat=4
although

seems like it may be a good option as well.

Basically, I am not that concerned with noise as the system isn't on at night or anything - I just want maximum cooling. My only other concern is that I want to be able to literally unplug the current stock fans and plug the new fans into the same socket to avoid having to re-wire etc.

On a separate note, I have another system that is using an h50 - would it be possible to put two fans on that (push/pull) or would there be problems?

Thanks,
Madals
 
Posted this in the wrong forum - if a mod could move it to the over-clocking and cooling forum I would really appreciate it :)
 
Both good fans, aswell as the apache blacks. get 4 of them, push/pull both your h50 and 70 and the temps will plummet.

Or, buy two and stick your stock corsiar fan from your h70 to your h50 and have push pull that way.
 
Try and get a fan that is optimized for higher static pressure.

The CFM ratings are for open use, but when trying to force air flow through a confined space such as the fins on a rad, a higher static pressure is better.

how do you know which is best for higher static pressure? lower or higher numbers? what is the best fan for static pressure?
 
Another option I found (not on OcUK so won't link) is the Scythe ultra Kaze - its 3000rpm but puts a massive 130CFM air flow (can't find anything on static pressure). Problem is they are a lot louder and I am not sure its worth it.

When you say get 4, do you mean 2pull 2 push or just 2 for the h70 and 2 for the h50 :D

Also, thankyou Stulid they were really helpful links - so the viper is the way to go then!

I replaced my H70 fans with Noctua P12's (high static pressure) and it dropped the temps about 8-10'c at full load and they're virtually silent but they do cost a bit!

Does push/pull really make that much of a difference, how much will it generally reduce the temps by? I might buy an additional fan if it makes a big difference.
 
 
Thats exactly why you should always check the manufacturers website for the correct info than just the shops shoddy use of a decimal point.

I'm not a complete believer in static pressure resulting in lower temps. Iv'e used both the Akasa and the Noctua fans mentioned on my Thermalright Venomous X and I can tell you in "real world terms" I only noticed a reduction of 1-2 degrees using the Akasa. I settled on using the Noctua NF-P12 because the Noctua is so, so quiet it was a better option for me for 1 degree higher.
I'm sure this will all depend on the case used and other air flow reasons but for me in a HAF case (fully loaded with fans) higher static pressure is negligible on my heatsink.

The fins on a radiator are a lot denser than a heatsink, so it needs good static pressure to force it through.
