I finally got around to putting together my loop and my 480 UT60 has a big dent on its end. I could have sworn I checked it over when I first got it, but apparently I didn't do a good enough job. I ordered the radiator from Performance PCs back in December. I sent an email to Alphacool. They're telling me I need to go through Performance PCs. Performance PCs is telling me they can't do anything for me because I'm past their 3 day return window. They also claim that the dent won't make any difference. I'm going to keep on both of them, but am I just out of luck here? Seems ridiculous.
