I have an older Lian-Li V1020 with a Thermalright HR02 cooler with fan and
there is lots of room for
a taller than 170mm Cooler.Most of the time it is the Air Moving thru the
case as well as the right Fan on
an excellent cooler that makes the difference in OCing. I have my I-7 2600k
overclocked to 4300 and even under
stress for 2 or 3 hrs it never gets above 75c..normal everyday temp is mid
30's
And of course it depends what chipset/CPU your thinking of and the end use
of the unit
My 170mm in an all aluminum case, both old, runs ambient room for the
summer temps, so far. Stress for a measly first generation Intel
dual-core, tops out what the HDs run - 109F.
There's also a new generation of 170mm coolers running sideways,
linearly over the MB - not upwards and across the width of the case -
with two assemblies, instead my one, core heatwick and supportive
fins, which also supposes, instead my two possible fin-mounted fans,
another one for a total of three CPU cooler fans. Looks, actually,
damn strange with a big-butted empty slot, with no 3rd fan in there,
or oddly off-balance, I suppose were either end-fan missing.
Just doesn't add up. That 170mm 2-stage fin-block, 3fan CPU cooler
costs $100US whereas my 1 (of two possible) fan 170mm Coolermaster, 1
fin-mass, I got for under $20 (rather I kept it on a returned/broken
CPU/MB deal and filed a credit card dispute on return shipping to keep
it that way, as I was in the right, and it's semi-standard practice to
absorb out-of-pocket expenses when the card-carrying customer can
prove dickery).
