Morning.


Well, the AC Freezer arrived as did the MX-2 TIM and the lapping kit so I'll be busy for a while tonight making a shiny Q6600 but I have a question.

Which way do I mount the AC Freezer in my Antec P180?

I have 2 options. I currently have the Intel stock cooler and both the rear top and top rear 120mm fans exhausting in the P180. When I mount the Freezer, one of the 120mm needs to come out due to space.

Option 1. Mount front to back.
I'd have to remove the top rear 120mm fan, but I could reposition it in the 5.25" bays to draw extra air into the case - seems like the most obvious soution.

Option 2. Mount facing upwards.
I'd have to remove the rear top fan, which again I could use to pull extra air in via the 5.25" bays, but this has another advantage (maybe disadvantage) in that it'll be pulling the hot radiated air away from my 80c idling HD4850 quicker. Obviously warmer air going into a CPU cooler will impact the performance, but to what degree (no pun intended)? I haven't got the space for a 3rd party cooler for the HD4850 unless I upgrade to a PCI-E Creative card, which means more cash, so if this is likely to benefit the GPU too then I'd be happy.
 
It's a little different for me as I can mount it either way facing an exhaust fan. Mine looks a lot different to yours.... ah it's Freezer Extreme (my bad)

Not my case but you can see what I mean.

If I face it backwards I have to remove the top fan due to clearance, but I could use that fan to pull air in through the drive bays.

If I face it upwards I have to remove the rear fan due to clearance, but it will be pulling stale warm air from above the graphics cards.
