    Alright guys this is my first post :) I have an fx8350 oc to 4.7ghz with a corsair hydro h60 v2 cooler running in an asus m5a99fx pro r2.0. I have a temp probe on the nb/Vrm heatsink and under full load the most I've seen from it is 36 deg C. From what people have said I must have a good board. I'm in the process of gathering all the parts for my custom loop. I just need the 2nd radiator, fittings, temp sensor, LEDs and thermal compound.

    I have a ASUS M5A99FX PRO R2.0 with FX8350, how did you get the H60 to fit?

    I just used the amd bracket that comes with it. In the spec list it says it fits am3 but not am3+ yet it fitted straight on. If it's the same cooler as I was using it has a bracket that has two screws with a kind of looped end that hook onto the original plastic bits either side of the socket and then you do up both threads until tight.

    And can also now add some more to the op of this thread. I've since fitted a custom loop so instead of having push pull fans right next to the vrm heatsink there's now only a sp120 quiet corsair fan at the rear with a 240mm rad in the roof. Huge difference now. Even at 4.5ghz after 7m of prime 95 the CPU is nowhere near max temp yet it drops the multiplier down to 7 from 22.5. I fitted 3 40mm fans above the vrm and nb heatsink and it did nothing. When running stability tests I have to cable tie a 120mm fan pointing directly at them and then it's fine. Interestingly I can play bf3 or 4 np without the 120mm or 40mm fans pointing at it and it never throttles. I also found pegging the ram back from 2133mhz to 1600mhz and 1.5v from 1.6v helped a lot too. I would get a crosshair if I was keeping it long term but early next year I'm going to use this board, CPU and ram in my 2nd PC in my room with the h60 on it and going for the asus maximus vii formula and 4790k hopefully.

    Also to add my 2nd PC has a gigabyte g-970a ds3 board with no vrm heatsink only nb and sb. At stock 4ghz with my fx8350 (which it doesn't support but runs perfect anyway) after about 5m of ibt it throttles back. CPU nowhere near max temp but the usual suspects almost burning my finger. This in a air con 18 deg c ambient room too. I'm fitting either a phenom ii x6 1090t or fx6300 in it so I'm going to add some of those self adhesive copper heatsinks to the tops of the vrms to help. Will also have 2 fractal 140mm fans on the side panel blowing at it as well.
