How is your case airflow? You may not be supplying it with sufficient cool air.
I have Corsair-SPEC 01 with one 120mm in the front and back. Is that enough ?
Thanks for you answer
The Front should be acting as an intake and the rear as exhaust. Make sure they are the right direction.
Are they PWM fans (variable speed)? You'll know if they are 4-pin. Your motherboard should have utilities to change the fan speed curve, if they are PWM. Try setting a more aggressive curve so that operate at 100% at low CPU temp. Such as 25C. Then use the utility for your video card to change its fan speed curve so it hits 100% at say 50C.
Those temps are low for such a high setting and will be fairly noisy. It will let you know if you GPU and case cooling is sufficient to attain a safer operating temperature. This will let you set a baseline to start tweaking fan speed for an optimal balance.
If you can maintain a safe temperature. Then you can look at adding case fans to reduce noise. Higher quality fans generally move more air with less noise.
By the way. The Corsair SPEC 01 has dust filters. Those fans should have a decent static pressure to overcome resistance. Arctic F12 PWM are good budget options. They also have a value five pack Arctic F12 PST PWM. The PST models allow daisy chaining for multiple fans off one header. They are not the best but perform nearly as well as fans near three to four times the price (looking at the bulk 5 pack price). They also do better in the noise to CFM ratio in restricted airflow conditions than many of the big names in case cooling.
