So the fan in my Peavey Alphabass is a little noisy, not noticable when playing but as a cheap component I thought id replace it. The original looks like a 80mm AC 230v fan. Are there any other specs id need to match when sourcing a replacement? Our local PC store has what looks like good replacements for literally £2-£3. I just want to make sure that other than size, AC and power consumption theres nothing else i need to take into consideration? Here is a pic or the original:-
