I have the 200 mm front fan sucking air in. 200 mm top fan blowing air out. 120 mm rear fan sucking in. I also have a hyper 212+ cooler sucking the air from the rear fan into the cooler. I don't know how to use realtemp but it seems like the minimum temp is 25C and max is 40C.

BTW, my temp seems kind of high for just browsing the web. Should I redo the cooler installation?

thanks

Looking at the picture, I'd guess you're supposed to have the rear fan as an exhaust fan...not an intake fan. Why not add the 200mm side fan for extra cooling. It's nice to have one blowing cooler air on the CPU/GPU while having good exhaust flow as well.

Expected air flow from your fans:
(from CoolerMaster)

200mm fan 110 CFM @ full rated speed.
120mm fan ~45 CFM @ full rated speed.

40c max is great, my idle is 35 but I never hit above 55c on a stock i7 920. I have my fans on the bare minimum though :)

Your temps are going to depend heavily on the ambient room temperature. If the room is warm...your temps are going to be higher than they'd be in a cool room.
My build USUALLY idles in the high 20's to low 30's, but if I don't turn on the AC on warm days...and the house warms up into the low 80's,(F) then my build temps rise into the mid-to-upper 30's.

Hmm then what about the Hyper 212's fan? Should I be facing the rear fan and blow hot air into the rear fan. Or should it be facing the front and sucking cool air in? I'm thinking maybe the latter?
