Yes, it is. Ambients often go past 25, and even the worst chips can overheat. Get some monitoring software, like Speedfan, and find out.
Btw error occured last night again just this time it wont turn back on, i tried removing the power cable and hooking it back up after 5 mins no fix, tried unplugging the PSU and rehooking it up, still no result, i think it's done for good, just would like to know what the issues it.
