Yes, they're practically humping each other, although placing some clothespins between the cards to space them out reduced heat by about 4C on the hottest card, not to mention the air circulation in my basement is terrible. I figured that running them 24/7 was the best way to deal with hot cards.
As far as the boasting, Tiger Direct can suck it since they're employees tend to know nothing about anything (I basically had to explain their own warranty policy to them). And truly, the post was meant to be informative under the guise of being boastful. I figured this would be something miners may want to consider.
And I thought I was creative using clothespins for spacing. Nice!
