Hey Guys & Gals, this is my first post on these forums and I'd like to say "Hello" :D

I'm in a bit confused about the temperatures since my upgrade, and am seeking some advice as I've just spent out £1,500 in total.

My Specs are as follows:

Coolmaster HAF-X (with all fan locations used, fan speeds at 700 RPM)
Corsair AX1200 Power Supply
Gigabyte 990FXA-UD7 Motherboard (Rev 1.0)
AMD Phenom II X6 1100T @ Stock (3.3 GHz, under-clocked to 800 Mhz when idle)
2 x Corsair Vengeance 4 GB 1886 MHz DDR3 Memory (8 GB in total)
2 x VTX3D HD6990 @ Stock
Samsung 1 TB Spinpoint F1
OCZ Vertex 3 SSD
Windows 7: Ultimate x64

I switched my stock cooler to an Artic Freezer 13, wasn't very sure about cleaning the thermal paste; I used specialized cleaning water (which was de-ionised and contained no other chemicals) and it came off in a single wipe.

I attached the cooler several times with it's pre-applied paste, it took at least 5 attempts before I mounted it correctly without the clips falling under the cooler.

Now here is the strange part, when under full load the heat used to poor out of the top and back and the CPU maxed at 50c (was noisy), however with the new cooler it remains with no heat coming out of the case, the CPU maxes out at 55c (Or so I think, I question the sensors).

So first of all, Why does it run at hotter temperatures under load and yet expel almost no heat into the case? But then it runs at 33c when idle which is cooler than the stock cooler?

Surely a 200W Air cooler should keep the temps lower than the stock cooler under load as well as when idle (Stock I think is < 50W) and how can less heat be expelled into the chassis because heat doesn't just vanish?

I'm sorry for the amount of writing but one last question, Is AMD OverDrive reporting the total temperature of the CPU at 55c (It shows the same value by each core, or is that the individual core temps? making it even hotter in total.) HW-Monitor reports cores at 40c, and TEMPIN2 @ 55c.

Thank you in advanced for your replies, feedback is welcome and I'll check back in the morning as it's getting a bit late in the UK (00:47 am).
