gigabyte windforce 3x overheats

[pagona]

hi, one of my cards is hitting high temperatures and goes to REST untill it cools but it quickly overheats again. i am using sgminer5.1 and have 4 same cards on this machine, i cleaned gpu and conected fans to 12V so they are full power all the time but no luck, interesting is that it overheats just a minute after i start mining, any help?

Check to make sure nothing is blocking the fans, and that the fans are in good working condition.

If everything looks good, the next step is to replace the thermal paste.

fans are working great, i was thinking about thermal paste because it looks like heat is building up fast  but fans do not blow hot air out of gpu, how hard is to replace thermal paste?

It is not so difficult to replace the thermal past.

Can you reduce the voltage to reduce the heat? If you reduce the voltage by 10%, the power consumption will reduce 20%.

Thermal repaste is easy http://gpushack.com/blogs/news/47119940-thermal-repaste-guide

But be careful, gigabyte uses GLUE on its VRAM!

It will probably help temperatures  if you reapply thermal paste.  The Gigabyte WF cards are symphatetic
in that you only have to remove 4 screws.  Always be careful when you remove the cooler and fan assembly.
Also consider if this operation voids any warranty.
For thermal paste I have good experience using GC-Extreme.  Temperature diff before and after can be 10 deg or more.

my advice buy watercooler for your rig its the best choice .

i solved the issue, first my sgminer was showing wrong card overheats, after i figured that out, 2 of my gpus had fan module problem, fans were not spinning so i conected them to 12v all the time, then i replaced thermal paste on all of the gpus and get temperature down by 10 degrees on average. gpus are 3 years old now

thanks for sugestions everyone

The cost of waltercooler is too high compared to ordinary fan cooling. You may not have return on investment.
