When I installed the TR HR-03 Plus I just flashed my card to 659|2040 with a 1566 shader clock and called it a day. I moved to the TR HR-03 Plus because I couldn't stand my 61-64C idle temps, and yes that was even stock speed. The TR HR-03 Plus is great if you don't need those extra PCI slots. I still have one open at the bottom with it installed. Now I idle 45-47C and load 56-58, depending on ambient room temp.
If you want to keep all your slots and cool the card well, look into water cooling.
Below is a great thread for anyone new to flashing a GTX. The best approach is to edit the BIOS that shipped with the card and flash it in. Of course, folks should save said BIOS in its pristine state.
yes water cooling is ok. its not noicy... but my fan and HR-03 " Delta - FFB 1212 EHE" makes my gfx oc2 load at 56 cc MAX.. so its allot cooler than water cooling.. but omg its loud...
