well she has just had another tec guy come with another heat sink and fan that's 4 now.
after fitting it she made him test it for about 45 Min's with the new fan and it still got to hot under load with prim 95
even with it doing nothing it was at 58c while he was testing it.
tec guy just said take it back to Curry's and throw it at them as its not fit for purpose and should of been replaced in the firs place.
