I need suggestions for PWM 120mm case fans

That are $10.00 USD or less.

I'm sick and tired of the cheap 120mm fan I have in my case now and would like to replace the blue LED monstrosity with a fan that is quiet, and has no LED.

The fan does not have to be the quietest available because I won't run it at full speed until the CPU reaches 55C. Even under Prime 95 i rarely exceed 55C so most of the time the current fan I have spins at 50% of its capability.
 


How much more would I need to spend to get a decent PWM 4 pin fan?
 
Well with 95 CFM I guess I wouldn't need a front intake fan. I do plan on using this fan in the upper back near the cpu cooler.
You suggested disabling the fan I have now and see how it affects temperatures, I'm not going to do that at this time because its very difficult to reconnect it due to the tight fit between the back of my case and the Cooler Master Hyper 212 EVO, I can barely get my hand in there.
