Gpu overheating after few months of usage

[Aravind92]

I won a sapphire r7 260x 2gb version..Got it in the month of march..I also have a custom fan profile with msi ab i wihch i've set the fan to reach fullspeed once the card hits 80 c..Till july the card would top at 80 c..Now with the same games the card is reaching 85 c..I live in india,chennai..Previously when the card used to top out at 80 c the temp here was 40 c..now the temp outside is only 34 and the card is running 5 c hotter...What would be the reason for this?..will the cards run hotter as it gets older..Ran furmark at 1080 with 2xmsaa for 40 mins(topped at 93 c and stayed there)..Just wondering what it would be like in april/may..Should i complain to sapphire about this?...And there is no problem with cables in my cabinet and everything is absolutely clean...

i dont think its a cards fault the reason is high ambient temperature the amd cards are usually hotter than the nvidia but the main reason is either the room temp is too high and the case airflow is not proper so its bet to keep your pc in a ac room and always turn on the ac while playing the game you will notice a big change in temp with that and the card should be hotter than the ambient temp because if the card is cooler than the room temp then water droplets will form on it which is way bad......

 

[Aravind92]

Unfortunately i don't have an air conditioned room...Am pretty sure the ambient temp is lower than what it was when the card used to top at 80 c..Everythin in case is as clean as it used to be..My question is if its normal for a card to have higher temps after a perod of usage..?

 

[prit87]

80 c for amd card in a 34c environment yes its possible just set the GPU fan speed to 80% while playing games .......my friend have a gtx 760 and in a ac romm at 17-18 c the card hits 76c when he plays watch dogs....

 

[Aravind92]

No..When environment was at 40 c the max was 80 c on the card..Now its 34 c outside and the card is hitting 86 c with the same game...idle temps are normal as it used to be...i have the fan running at 100% speed...

 

[prit87]

well in that case u can clean up the card dust can be a reason for overheating....so remove the card carefully clean it properly and see if that helps....and you can always report your problems to sapphire.....

 

[Kari]

yeah, there's probably dust and other stuff in the cards heatsink, you might need to remove the plastic shroud to be able to clean it properly.

 

[Aravind92]

Everything is perfectly clean as i've told already..Just as new..no dust whatsoever...I remove the card and clean it oncein a month...

 

[prit87]

what case are u using ??

 

[Aravind92]

Its not a great case to be honest..But i've been using the same case since i bought the gpu...I don't want to change the case and decrease..My doubt is what would be the reason for the increase in temp...would it be the thermal paste in the gpu..?

 

[JRFET]

weak psu on rails....voltage drops current goes up vrms work harder/duty cycle etc excessive heat....

 

[prit87]

yea it may be the thermal paste but the chances are slim for that generally a gaming case should have 1 front intake fan 1 top exhaust 1 rear exhaust and 1 side exhaust for the card.....open the sidepannel of the case and put a high speed table fan blowing air to the gpu.......it will help in lowering the temps...

 

[JRFET]

or yes simple thermal paste/case cooling problems.

12v voltage is same as before...Drops to 11.6..it has been the same since i bought the pc...Now can we confirm its a problem with the gpu...Because everythng else is same...

 

[Aravind92]

Is it normal for a gpu to get worse within 5 months of usage...And one more thing is if i have to run games now i should have the gpu fan runnning at 100% all the time..Is it alright?

 

[JRFET]

11.6v isn't that great.....did you check that with a multimeter on 4 pin molex?? and is that under load assuming? need to see what its doing on idle too/how much of a drop etc....but i don't even like it being that low at all....

my old delta would get about that low even seen like 11.5v a few times and there was noticeable tendency for everything to be running hotter....and toward end everything was just running pretty bad...some intermittent things like it would not boot etc/restarts/freezing.

dropped in my new evga 600b haven't seen below 12.2v idle or loaded.... drop of 10-15c too after this....that's pretty significant....
running hell of a lot better also.

 

[JRFET]

the secondary on that psu has CapXcon caps too...

 

[Aravind92]

No i understand all that..I've checked all these as soon as i built my pc..My 12v was dropping to 11.6 since i bought the psu,i know that's not greaT..But the problem is evrything is same still except for the change in gpu temp..What would be the reason...?..And the drop from idle is .3v,that too is the same from the time i bought the pc...Your point would be correct if there is a drop in voltage and increase in temperature..

 

[JRFET]

how old is that psu?

 

[JRFET]

or maybe you just simply need to put some fresh/quality paste on that gpu and see what happens.

same..5 months..bought all the components together..

Can i apply thermal paste myself..Would it not void the warranty...

 

[prit87]

if u have heating issues with the card and its new so don't open the heatsink yourself send it to warranty and ask for a replacement ......

 

[JRFET]

You can probably do it yourself just get you some decent past like arctic silver 5/MX-4 etc, and add a small amount/drop, it takes very little.

Will it not void my warranty...?

 

[prit87]

it may i am not sure about it so its better u ask the local store from where you have buyed it first or the online site or directly ask the sapphire ......
