i'm planning to buy a CM Hyper212+, is it good? do i need to buy separate thermal paste? or just use the stock ones?

thanks

my CM212+ is reaching by tmr, and I've bought another 120mm fan for it. can anyone here show me how to setup push/pull for good airflow?

much appreciated!

my CPU(i5 750 2.66ghz stock no OC) idle temp is around 33-35C, 100% load under prime95 is around 55C. PC not in air-con room, can this temp be considered as OK?

I've set up push pull, but I've got a problem now. Both are CM BladeMaster 120mm PWM fans, 4 pins. I've connected the rear fan(pull) to the "CPU_FAN" socket, and it's running in PWM mode, fan speed is 1200-1300rpm idle, 1800-2000rpm 100% load. But the front fan(push), is running at very low speed(400-600rpm all the times, even at 100% load), I've connected to 4pin socket too, why is it still running at such a low speed? the speed doesn't vary at all even when full load! I thought idle should be at least 1000-1100rpm, but it's 400-600rpm in both idle and load, I don't understand that, pls HELP!

sometimes stock speed 100%load, it shoots up to 60C, ok too? when i OC a bit to 3.2ghz, idle is around 43C, prime95 100% load 65-70C, ok?
