Heatsink Factory received my order for a Prolimatech Megahalems cooler and Noctura NF-S12B FLX fan on Friday @ 1:51 PM. Shipped USPS priority mail(from Idaho to Arizona)the box arrived Monday @ 2:00 PM.
Before I placed this order I ordered a mobo, cpu and graphics card from Newegg for a new build. Well, the Newegg order is scheduled to arrive on Wednesday. I'm not complaining about Neweggs shipping but there is a point to this. Heatsink Factory was open for business on Saturday and I believe they got the package over to USPS before the end of that day.
The Prolimatech Megahalems is hard to find. There are only 5 vendors in the USA. Two of them don't sell fans, one was out of stock and the last one did not offer the Noctura NF-S12B FLX, which comes closest to the cooler specs of 1200 rpm and 57 cfm.
If you are looking for a Prolimatech Megahalems, use Heatsink Factory and experience their exceptional customer service firsthand.
