loud high-pitched fan noise, only when gaming

When I start a game of any kind a fan in my computer instantly goes to max speed. It is very loud and annoying. Is this maybe a wrong setting where it kicks in too low? What diagnostics should I run to determine the source and cause?
 
Maybe check temps with a program like HWMonitor, to see if there's some real reason for the fans to go crazy. If temperatures are spiking, then you'd go the route of trying to improve that - checking for dust obstructing the coolers, checking that the CPU cooler is seated correctly, maybe reapplying thermal paste...

If not, then it's the path of trying to determine which fan is going crazy and why - maybe the fan itself is broken, maybe there's some wonky setting that needs to be changed, and so on.

The temp never goes above 25 c (77 f). Are there programs that monitor fan rpm or do I just open the case and listen/disconnect 1 at a time?

Edit: correction: it's the graphics card. When I first ran HWmonitor it only showed system temp. I closed and opened it and there is a ton Of data. My card starts normal but even simple games (using FTL to check.. Its not even 3d) it spikes to 100 c (200 f) and the fans go yo 85% speed. Why would it get so hot? Does it need replaced?

Hw monitor showed me fan speed after. It's the graphics card spiking to 100 c (200f) as soon as a game starts. Any way to fix this? Does the card need replaced?
