HP OEM GPU, No fan control issue

[PartTimeApathet]

Hello

Picked up a cheap GPU for my gf to play Dishonored, the Sims, GTA; found an r9 270, a reference model. It is one from an hp machine (Hp pn 741521 - 001) that does the job just fine for her. 

 

Only problem is that the fans seemingly don't work correctly, MSI afterburner will tell me that they are running at whatever percent speed, but they will only actually spin up at 80 fan speed and will run as normal between 80 and a hundred percent speed.

 

Further still, in the AMD software, the usual fan tuning options are missing.

Personally, I own an r9 270x, which when swapped in, the fan tuning options are present.

 

I have heard that in some cases these OEM cards can have limitations on fan control like this, was just wondering if there's any way around this.

Having to run at nothing or 80% isn't that big deal, I only spent £15 on the card, it's just a little annoying. 

 

Any help appreciated.
