Okay, well ive made a couple of changes, cant find any short nose pliers to get the chipset heatsink off at the moment, so ive put that on hold.
Ive cleaned off the arctic silver and had realised i had used a really old tube that had been opened for ages, i reapplied with a smaller amount after cleaning the heatsink and the cpu, ive moved the pc from the desk to the floor where its cooler.
I noticed before i started that it was idling at 50-51C, possibly because of a few things, low airflow in the pc, the fact my wife has the room like an oven, its sitting about 27C in here at the moment, the sweats running off me
the pc is completely silent too, you could literally hear a pin drop all the fans are so quiet.
Anyway, idle now is 43C, much better. The NB is down from 54C to 45C too, so a good drop there, but i think ill still get the typhoon as it would cool the chipset too, since its right by it on this board.
