Question Modding my old EVGA GeForce 8800 GT video card's fan to blow heat from the PC case?


I have an old EVGA GeForce 8800 GT video card's fan in a brand new Antec Sonata Proto mid tower ATX case with two case 120mm case fans, MSI P43 NEO3-F (MSI-7514) motherboard, etc. See for the details for this secondary computer. Also, hardwares were cleaned last night from its dusty after about two years of usage.

I noticed this video card's fan goes to maximum speed (over 5,000 RPM) even when my computer is idling. I think its air flow is not good in this new case. I know my old MSI ATI Radeon 4870 video card (512 MB) blows its hot air in the rear, but this NVIDIA card doesn't. Is there a way to mod its cooler to blow out heat?

FYI for my system's sensors:
$ sensors -f
Adapter: ISA adapter
Core 0: +143.6F (high = +176.0F, crit = +212.0F)

Adapter: ISA adapter
Core 1: +140.0F (high = +176.0F, crit = +212.0F)

Adapter: ISA adapter
Core 2: +141.8F (high = +176.0F, crit = +212.0F)

Adapter: ISA adapter
Core 3: +147.2F (high = +176.0F, crit = +212.0F)

Thank you in advance.
