I've bought many Xigmatek fans/heatsinks with rebates and they are all decent products. One thing about Xigmatek rebates is that it is extremely slow and I've had to contact them every time to get paid (and you can not inquire about the status until it's been AT LEAST 16 weeks after the end of the promotional period (not the date you mailed the rebate; most Xigmatek rebates last 30 days). I think a lot of customers probably forget about the rebate by then.
