How much did temps drop when you reversed the fan? Re HSF ,Ebuyer do a Cooler Master CP5 6J..... (etc) ,has a copper base & is rated upto XP3000.It only costs about £7 ,that would be a cheap & worthy upgrade.....unless your willing to spend £30 on a big all copper HSF
chip temp 52c system 35c Thankx will have a look.
Right ,so thats a drop of about 4-5C,not bad for a freebie
