Yes it's more than a fair price, its a sick set up. I love the cooler. I always wanted to try the silver arrow! Good luck with the sale.I think I may just use this as a server/htpc soon if it doesnt sell. I dont think I am asking a lot at $520. New this kit is at least $800 + Taxes.
The mobo I bought in Jan, the Cpu, Ram and HSF in Sept last year. It is all mint.
I only ever overclocked this cpu using level up to 4.6ghz as it was more than enough for me. Never oc'd the ram, just used the XMP profile. I dont think the cpu ever saw temps over high 60's low 70's using the silver arrow when oc'd. At default it never was higher than low 50's.
