I bought a powercolor radeon 250mb x850xt in april, but experienced artifacts at temps of 50 celsius. Went ahead and fitted a zalman fan, yet this only reduced temps by a few a degrees, and was only a temporary fix since the card soon went back to graphical anomalies at around the 50 degree mark.
The card is under warranty, although I need to stick the stock fan back on, which I no longer have since I thought that I'd've voided the warranty and would have no need to replace the inappropriate fan.
Is there anywhere I could get my hands on a stock fan for this product?
