Subject:   GPU running too hot ?
-------------------------------------------
I have an Inno3d GTX 550 Ti and I play Sleeping Dogs which uses the GPU to 99% and when using a stock cooler it peaks at 90c and even using an aftermarket cooler with 2 big fans and 5 heatpipes on 60% fan speed it peaks at 83c ( I think it's the max coz it won't go any faster I try to type 100 but it goes back to 77 ). Isn't this too hot for this card ?

This is how my VGA cooler looks like

TBH no. Graphics cards are able to withstand higher temperatures than processors. The thermal max (or tjmax; the specified max safe operating temperature) is 95c (that number will vary from model to model)... Usually you'll get warning signs when your card starts getting too hot, that is a sign to close the game or increase the cooling. 90c is fine and shouldn't cause issues, but that is too close to 95c for me (not alot of headroom for my liking).

But is this normal ? Coz I've seen reviews and temps never went this high. I know they used a different benchmark method but still.
Oh and the idle temp of the GPU using my aftermarket cooler is 46c, hot ? It's night now here in my country so ambient temp should be low.

Like this review of Neoseeker http://www.neoseeker.com/Articles/Hardware/Roundups/nvidia_gtx_550_ti_palit_msi/18.html

I updated my post. On your stock cooler I would normally be concerned since there is only 5Âșc gap, but with your aftermarket cooler on, you should be fine in terms of if it will overheat or not.

In terms of the temperature in general, it's hard to tell without taking into account case, fans and their setups, etc, so there could be multiple reasons.

The air in those video cards is sucked in through the fan and channelled out through the back of the case (hence the two mounting slots it takes up on the back), otherwise the single slot fans just chuck the hot air back into the case. Not actually used an aftermarket cooler in that respect though so I'm not quite sure how they're set up.

ill admit, 90 degrees is high, but its still safe. however, i would still take a look around in your case, to see what might be causing the higher temperatures. does your case have dust in it? anything obstructing the airflow in the case, or near the card? does your case even have fans? is your room usually quite hot?

The 550 ti runs a little hot on average compared to some cards. Still, you probably need to blow the dust out of the heatsink on your GPU and also reapply some new, high quality thermal paste.

Is there any cards directly under your video card that could impede airflow? Could you add a case fan somewhere around the video card to help draw away heat or blow cool air on it?

Try what Iceguy suggested and reapply some quality thermal paste (such as arctic silver).

The heatsink is very clean just cleaned it before putting into the card. My case isn't a gaming case but isn't 15c difference a little bit too high though I haven't researched about cooling yet so I may be wrong.
Can anyone give me a suggestion on proper cooling ? especially on this card. And, how should I place the fan of the VGA cooler ? sucking or blowing the air ? I placed it so it will blow the air.

Okay I saw this http://icrontic.com/article/pc_airflow_heat_cooling_guide and I'm going to experiment.
