Concerned about Gpu temps, should I be?

[Mentaltoast]

I just finished a new build, my own dream computer.

 

Lately I've been obsessing over the temps and have some concerns though I'm not sure if they're really worth having, was hoping for some more experienced user's input.

My concerns:

 

My fan set up consists of the kraken x61 rad being mounted on the front of the s340 case, with the fans pulling in from out of the case, through the rad into the system. then I've got the stock 140mm exhaust on the rear and the top.

Since I'm not super experienced I didn't consider the issue that the rad being front mounted would be blowing somewhat warm air onto the cpu rather than clean cool air. I've opened the side panel and it doesn't seem that warm, seems still kind of cool however I'm no scientist and it's probably still far from ideal. (which seems strange as this is the only mounting option and nzxt themselves recommend the x61 for this case)

 

 

My temps from what I've observed as follows:

 

Idle; Cpu- 20-25c, kraken liquid temp ~25c.

       Gpu- 46-50c

 

Under heavy load : Cpu - rarely ever higher than 50c. 

                              Gpu - 74-80c at 100% load

 

Whenever I play a graphic intensive game, say Bioshock:infinite or Far cry 4 with maxed out graphics, the gpu bumps up to 97-98% load and the kraken's fans have to spin up to 100% to compensate. This causes the front fans to be VERY loud which is quite annoying as well.

 

I'm not so much worried about the cpu temps, they seem very nice for what I'm getting compared to my old computer, though the mid->high 70c on the card whenever gaming and the fact that the fans have to go up to 100% just to compensate have me a bit worried since theres no more room for cooling after that point and if the card ends up getting hotter than 80c and keeps climbing, theres no way to increase the cooling to help it.

 

Am I just being overly paranoid ? Are these temps more than reasonable and I should be content with them? Or am i justified in having some concern, especially for next summer when the ambient temperature will be quite a bit warmer?

Those are normal temps.

 

Edit:

However not at 100% fan speed.

[OAcesync]

It's fine

[Comessy]

They make is so it will go as close to 79c without going over

You should only really start worrying if your temps start going above 90°C.

Check your fan profiles. I had 80C temps under load (GTA/The Witcher/etc.) on my 980 until I made a custom profile in MSI Afterburner. Now I'm at mid-60's.
