Is it worth to apply CLU to GTX 1070?

post #1 of 9
Thread Starter 
I'm getting Gigabyte 1070 G1 card soon and am wondering if replacing the thermal paste with CLU or similar top performance paste would decrease temps much.

Have you had experience in upgrading thermal pastes on current or last gen nVidia cards?

I don't know as far as Nvidia, however make sure you understand that CLU isn't paste. It's literally gallium which is liquid at room temperature and you basically are soldering your heatsink to the chip. It molecularly bonds to the metals and can never really be completely "cleaned off"


That being said, I have used CLU on 2 AMD R9 290 cards and a 2011 i7 with great results.

There aren't HUGE gains to be found on a GPU since the die is pretty big for the TDP but in my opinion I'll take whatever I can get.

I did a thread showing pictures of the process for anyone wanting to see what CLU was like before going that route

I'm pretty sure my GTX970 died from using CLU... I tried to use electrical tape to protect the caps on the sides of the die...I think some might have infiltrated underneath the electrical tape and dissolved a cap or 2... So beware if you plan to use it...make sure you use proper protection...for the caps sake...

I'm debating using it again... I might pick up a new GTX1060 so I likely won't go through the hassle of applying it for a card I'll sell in a month... I probably will with my 1060...lower temps at all costs....

I tested this on my MSI 1070 Gaming (non X). Made no difference when I compared before/after temps. Don't bother to replace the thermal paste with CLU. Just asking to destroy your GPU for no gain at all.

Then you did something wrong... did you use a custom fan curve? What it probably did if you had stock fan curve is it kept the same temps but drastically decreased your fan RPM since it's way more efficient...

No everything was the same. No change at all. Like I said, not worth it.

I own a G1 1070 and honestly it only runs around 62C under pretty heavy load (Witcher 3)

Not worth it.

Thanks for the tips folks. If gains are much smaller than from Intel CPUs (10-20 degrees cooler) I will only place CLU once my warranty goes out (after 3 years).

I agree, unless the TIM was applied wrong then it most definitely should have dropped the temperatures.
