Time to share my results of the cpu (4.2Ghz HT) and mainboard highest temps at full load on a CM690 with 4 intake fans, two rear fans, cpu cooler in sig. and the two top fans likewise:1. Initial: Two Top Exhaust
max core temps: 77 74 74 702. Second Test: Two Top Intake
max core temps: 77 73 73 703. Third Test: One Top Intake with Second Blocked
max core temps: 76 72 73 70
All the times I used the same ambient temp @18°C, same settings for cpu, ram and chipset, fans at full rpm and the same (most) intensive cpu stress test, Linx v. 0.6.4 with the problem size of 25000.
As you can see, the recommended 1 top intake with the second blocked position wins this time too with slightly better cpu temps and nice mb & chipset temps. The two top intake fans would give me same temps as two exhaust but higher mb & chipset temps. And I still have to cut off the rear grill.
Now I'll have to do one last test, swapping the noisy Scythe Kama Flow 2 135mm @1600rpm side panel with the NB 140mm @1100rpm from the top blocked position. But first I need to test my two gpu's higher temps too. Edited by arrow0309 - 1/31/12 at 12:29am
