I put an arctic accelero extreme 3 on mine a few months back. It was actually a massive improvement in terms of operating temperatures and noise. The only problem was that it dumped so much heat into my computer chassis that I had to run my HTPC with the cover off until I replaced the card with a GTX 1070 last week.
I should have thought of that before I bought it really, but I had no idea just how much heat this card can put out when it's not being ejected from the case. The thing gets HOT when your case doesn't have the ventilation necessary to get rid of the heat fast enough. Of course I was working with HTPC class cooling, which is more noise oriented than airflow, so YMMV.
