Volt modding fans?

post #1 of 9
Thread Starter 
Is it possible to volt mod 12v fans to give them more volts for more RPMs? Noise is not an issue the stock HSF on this PresHOT already makes it sound like an F5.

Sure, most fans are rated to run up to at least 13.2v. Some can do even higher but will burn out sooner. However, you need a dedicated PSU to provide anything higher than 12v safely.

if you want more cfm and dont' care about noise. go get a

vantec tornado

or a thermal take smart case fan. which are like 75 cfm.


but other than that don't over volt your fans. they will burn out

Read somewhere that this may negatively affect your PSU's line regulation abilities.

Is there an easy way to do this lol?

I have my TT120 stock fan just on the ground, waiting for me when i get back from my runs around my neighborhood to cool me off while i watch house on my PC.

That thing is powerful, but could it be more powerful without digging into the PC? Like anything i can just do to the fan itself?
