Case Fan Cooling

So I have reseated my Scythe Mugen 2 twice so far (what a pain) and am still not getting what I would consider great results. The cores on my i7 920 touch 70 C at 3.1 GHz under full load and I would like to do better.

I realized that a more obvious problem is lack of overall cooling in my case (Hiper Osiris). I have 3 pretty snazzy looking yate loon LED 120 mm fans (1 intake, 2 exhaust) but they only put out 38 CFM. I know I am asking the obvious here but I assume that I would benefit greatly from some more powerful fans. I love how quiet the fans are but I really need better heat control .

How much would a change in case fans benefit me and what would be a good CFM to shoot for. I could shove some 100 CFM fans in but I really would like some sort of balance on the noise level. I see other yate loons that are rated for 47 CFM (28 dB) and 70 CFM (33 dB) that I could pick up for cheap but I thought I'd ask before I make a change.

Have you checked the official Intel thermal specifications for your cpu?

Yate loons from Petras are never a bad solution for better fans. Give em a try. There is reasons due to supply channels why Petra has the best ones.

Fannage matters with the new hot stuff like an i7 and a dual chip GPU.. Look at the better popular cases, it's fannage all the way.

You stated the obvious, now go do it.

Gentle Typhoons are all the rage right now, awesome fans, try to find them tho, hehe.

You have petra yates. Which ones? They sell 3 different speeds.

Yea, they are low CFM. I run mediums and fan controller them. Lows might be a bit too low, especially if there is a lot of metal case mesh or a filter blocking flow.

The highs are also very popular and undervolt nicely too.

its very easy to monitor temps. These show CPU and core temps.

HWMonitor
Realtemp

Both of them work great with the i7, get the latest revision.
