Thanks. I was looking at the Scythe Slip Stream on Amazon too.It's £10. I'll get that and see if it helps at all, and then go for the third-party cooler... I'm pretty sure my rear fan isn't doing its job. I can't even feel teh air flowing out of it wheni hold my hand.
if it doesnt help much I suppose taking off the vent and getting a good cooler is the best bet.
I don't really want to spend £60 on a water cooler as it would've made more sense to go for a more powerful CPU then... I built this rig recently on an emergency budget
thanks again!
