I have 730khs stable - 70 degC - fan at 2000rpm ( it's like 20% - so it's silent).
GPU clock 1035 MHz
Memory - default
Voltage - lowered to 1.1V ( and powertune -20 )
Card is Sapphire R9 280X dual-x OC

flash the bios, the vcore is probably too high
I set up an domestic ~30cm fan for my 3* R9280X rig, because there is weak ventillation in the place where it stands. For cost of 0,7 kWh/day i have nice 70-72 C temps 
It will become even more important, when I install 4th GPU soon.

good

Nothing wrong with those temps, some of mines are running around 90°C
Im running 85-90 degrees mining an r9280x. It sucks, but the other option is to not mine 
. Hopefully it holds up I heard the cards were Mac trucks when it comes to heat, we shall see.
. Hopefully it holds up I heard the cards were Mac trucks when it comes to heat, we shall see. I have the same cards with the same problem. On slot 1 pci-e 3.0 card runs 12 degrees hotter than the other on pci-e 2.0. Voltage is locked unfortunately. I hope we find a solution soon.
is there any method to unlock voltage?
i have done that with trixx for sapphire. Maybe it will work with your card. My card is Sapphire Vapor-X R9 280x
I need some help with the config. I only get about 560 kh
here my config
cgminer -o stratum+tcp://coinotron.com:3334 -u ** -p ** --scrypt -I 20 -g 2 -w 256 --thread-concurrency 8192
1038 GPU
1500 Mem.
Big Thanks
set -I 13. also on your oc software, change clock speed from 1100 to 1050. And my gpu memclock was by default set to 6000. So I left it untouhced. See if that works for you.
Add custom cooling and you should be fine. My 7950s ran fine at 80-84c.
ignored my question eh ?
PS: i already knew the answer anyway i was dropping a hint

bad fan design by me. Lol. So I added a fan and temps dropped from 84 to 74. Is it good enough? :p

try lowring the I to 13 cuz you have g to 2

I bought a new gigabyte r9 280x and I started mining. so it was only giving me 580khash/s on ltc mining. So I installed OC Guru II and in it. I changed gpu clock from 1100 to 1050mhz and memory clock was by default 6000 mhz.
I'm getting the same results on Gigabyte R9 280X and downclocking to 1050, but Gigabyte has the best cooling system - my temp is 70-73 C. Also I have PowerColor R9 280X: 1100Mhz/1500Mhz, 750Khash/s. Overheating! 85-90 C. It has a stock AMD cooling system.I dont get why downclocking is getting more khash/s. But anyways, I get 730kh/s on 80 temp. I am not sure if this will burn the card lol.

I've been hearing alot about issues with the new r9's as far as heat go. If adding airflow and changing the fan profiles doesn't help you may be able to put an different bios on it. I don't have a r9 so I'm not sure but you may even be able to use a 7970 bios with less voltage. Moral of the story... stick to 7950/7970 for mining for now they are basically the same card anyways
i wonder what fan setup your card has.. reference design ?
