120/140mm fan help :)

post #1 of 7
Thread Starter 
Folks

Thinking of buying new fans for my cpu, and Im thinking about going with a 140mm fan for my cpu, as some have 120mm fittings, like this:



But im thinking if its 140mm fan and its overlapping the cpu heatink (assuming they fit), will there be less actual airflow going into the heatsink, seen as the fan will be overlapping, or wont it matter?

On my heatsink I wish my 92's were bigger. They don't cover the whole assembly. Even if the fan is slightly bigger than the heatsink it will still be blowing on the tops and bottoms of the heat vents which will never be a bad thing IMO.

You might not be able to fit them on, since the megahalems is only meant to take 120mm fans.

Scythe ultra kaze + speedfan = win

Runs at 1k rpm when cpu isn't doing much and is mostly inaudible, temp ramps up and the fan can go up to 3k
