Trouble controlling GPU fan speeds

[JuggarJones]

The temperatures are fine, a maximum of 55*C on a maxed out, modded Skyrim with shader mods. My friend has the same settings, but gets a temperature of around 65*C, although his graphics card is much quieter. His GPU keeps to around 2000rpm, while mine goes insane at 4500rpm. I wouldn't mind slowing down the fan, making it quieter, if it means I go into the 60s in temperature.

So far I have tried numerous programs, such as AMD Catalyst to set a manual speed, and also MSI Afterburner to set a manual speed and a custom curve graph. Sadly, the 2000rpm quiet state only lasts until I play demanding games. I don't know what it is, but something seems to overwrite the custom settings, and decides to set the fan at 4500rpm to keep the GPU around 49-55*C. I have checked the BIOS, but I saw nothing related to graphics card fan speeds, but maybe I have missed something.

Any help would be appreciated as I have had this problem for as long as I can remember, but as I update my Steam game library, I encounter this problem more often! I have an MSI Radeon HD 7870 2GB if that helps.

This may sound silly but you have ticked the auto button AND the little user cog to highlight the fan speed bit of AB in green havnt you?

Indeed I have. I have also tried without ticking the auto button, but nothing seems to change.

Certain MSI HD7870 have a faulty transistor which needs to be removed before you can control the fan speed, I'll try and find the link for you as I had the same problem. It's very simple, takes two minutes and a sharp knife.

Just cut the highlighted piece off the board, or if you don't want to do it yourself I think you can contact MSI who are aware of the issue.

So you've done this and it worked for you? I'm guessing my warranty has expired as I bought the card 23rd June 2013, so pretty much just over a year ago. I'll read into this further and I will probably end up doing this. Thanks a ton though! I thought the probably was with bad airflow or something!
