I'm playing around with an Asrock Z77 Extreme4 and a 2500k. The problem is (was) that my trusty Thermaltright Ultra eXtreme 120 only has mounting gear for socket 775 but fortunately the board has 775 mounting holes, so everything is good right? Wrong. The mounting hardware directly interfered with the footprint of the cpu retention latch. The Thermalright backplate could maybe bend around the stock backplate but rather than bend it up anymore than I already had I opted for full removal of the cpu retention mechanism. It seems to work fine? No idea if I'm getting enough pressure but the screws are way tighter to turn than they were on my PK5 Deluxe board. Had no thermal paste but went for it anyhow. 80C in Prime blend set at 4.2GHz@1.28vcore. Noctua paste is in the mail. Hoping for a solid 10C drop. Anyways, is this a common practice? I'm very afraid of any vibration or impacts right now.. how long term could something like this be?
