Are my 280x temps too high???

Hi!

I have a r9 280x crossfire set-up for my rig. While the results are most impressive , the temperatures I am getting really bothers me. When I play BF4 card 1 operates around 79-85 even and card 2 operates around 68-72 ,both set at 100% fan speed. I have heard that this is how it was designed while others have claimed that I will destroy my card. Either way, its a little high for my taste. I have a thermaltake Mk-1 Chaser case with 2 top and one side exhaust fans ( all 3 200mm ) and one intake fan also 200mm. I do have another intake since my externally-mounted radiator also blows in a little air through the perforated metal.
Anyways, are those normal temps? If not, what can I do to keep them cooler?
I was thinking of hooking card 1 to my cpu L/C loop but I don't have the time to take apart my loop and install it and everything. Maybe later on like during Christmas. But ATM, I need to find an effective solution without seriously ruining my aesthetics. So please, I would Really appreciate any input.

At least my computer is a great furnace lol.

I don't see it listed, but what kind of cards are you using? are they dual fan style cards? I'm assuming yes, which explains why the first card is hotter - it's cooling itself with the exhaust air of the secondary card. there's really no easy way to fix that, which is why I use reference coolers only.

that said, if your max temps are 85C, they're tolerable. I would not worry about the cards dying. if you want to OC them, then start caring.

I have 1 MSI r9 280x which is gpu 1 and a gigabyte windforce 280x as my 2nd gpu.
I don't plan on overclocking at least not in the near future. But like you said AMD's specifications match the 80. They are said to max out at 85. Past 85 I will be damaging them, according to AMD. I'll try adding another fan somewhere ,but since its an r9 280x I doubt its going to get very much cooler, unless if I L/C.

Where does it say that temps over 85 will cause damage? I highly doubt that wording exists in any form - but i'd be happy to be proven wrong.

IIRC the 2x0/x chips will downclock to stay within their thermal/power envelope long before they destroy themselves.

I would love to give you a link ,but unfortunately I can only relate to a member who posted on a post in Tom's Hardware regarding a similar concern. He is a experienced member with a few badges so thats why I took his word on his post. But if you think about it, it makes sense that it can handle those high temps, because if you recall, the r9 series was hitting 98 celsius with stock cooler. And AMD didn't really have a problem with that. And I recall reading something somewhere that AMD stated that it will not damage the card.
But ya... sorry I don't really have a link. I just constructed that comment based on other people's posts, because I actually read similar comments about max temperature for 280x by other people as well. And of course I think we all remember the famous heat issues at the launch of the series. So if it would not have been able to handle it I doubt AMD would have released that version. Regardless if it was "meant" to withstand the heat, I believe it does reduce the life span to some extent. So that's why I'm looking to cool it down a little more.

Take comments on temperatures with a grain of salt. there are a lot (that's a scientific term) of people that will pick a temperature, and say "it's too hot", with no basis in science or fact. yes, 85C is too hot for a human being, but GPUs aren't people.

AMD optimized for both noise and thermals - the hotter you run a chip (and therefore the heatsink), the more heat (energy) will removed by the same volume of air through the heatsink. Would it be "ideal" to keep the chip super cool? sure, probably. is there a serious problem running a stock GPU inside of the stock thermals as designed by AMD? I don't think so.

Lots of people are concerned about lots of things, but it doesn't mean there's good reason to be. Now the moment you throw "the book" out the window, start upping the voltage and cranking the clocks, then yes, you need to start caring about temps. so long as you aren't having performance issues, I wouldn't worry about it.

Thanks for the reply, u3b3rg33k!

I think you made a very good point and actually convinced me. I think I have to agree with you about the safe operating temperatures and people's opinion. But of course with overclocking another cooling alternative would be required.

Thanks
