Akasa 965's are a bogs dollocks
Far better than the AC7 in my opinion! Fit's just like the standard Intel cooler. Make sure you place it so the fan faces the RAM (this way it pulls col air in and gets pulled out the back and out again by your rear case fan - I can post a picture if you don't understand)
Best thing for testing your OC and it's stability? Prime95, CPUz and Core temp. Run CPUZ to check the OC and v-core (remember, all motherboards suffer from a thing called "v-droop" and it varies from mobo to mobo), if the speed is jumping up and down then there's still energy saving going on, so you must turn it off.
Then run Core Temp to check core temperatures (duh) and check CPU load.
And then last but not least, run Prime95 stress test "Blend". This will test your RAM, mobo and CPU stability. Once it's started running you'll see your CPU load reach 100% on all cores. The test will continue until BSOD, frozen, core failure or until you tell it to stop.
- BSOD depends, it can be RAM or CPU stability. Usually adding a little voltage to each helps.
- Core failure usually means the CPU needs more v-core, but it can sometimes be NB as well.
- Frozen is usually NB needing more voltage.
If no errors appear within ~6-8hrs your OC is generally classed as 99.9% stable. Although, a lot of PC's can run fine and fail this test. It's just 1 of those things I guess. Depends how solid you want it.
