overvolting a pc fan
overvolting a pc fan
Hi guys
do you know how to increase the voltage for your megaflow 230mm fan? It runs at 700 rpm and that’s not enough for you. You’re wondering if there’s an aftermarket PC fan controller that can boost the voltage for better performance. If you want it to spin at 1000 rpm, you’ll need to consider the impact on its lifespan. Let me know if you need more help.
Thanks in advance
There is no practical method to increase the voltage of a 12V fan in a PC, as the power supply already delivers that voltage. Custom solutions would be necessary, such as modifying laptop adapters to extract more power, but these would be complicated, costly, and probably reduce the fan's durability. A more suitable option is to choose a higher-RPM 230mm fan that fits your case.
operating the fan at its rated voltage will cause harm to it. be sure it isn't undervolted, as that seems to be the case.
i connected it to my motherboard's 4-pin header and its speed is at 100 in using speedfan software.

big fans tend to move slowly because they are large and can handle a lot of air already. These aren't inexpensive, and they're not as common as smaller ones like 140. I wouldn't risk it.
so you're suggesting that an aftermarket fan controller can handle 18v or 24v
You can purchase a voltage boost converter like this one:

This device enables overvoltage up to 35V (which would instantly destroy the fan).
The majority of fans are rated for up to 13.8V, allowing safe overvoltage up to that level or beyond, though doing so greatly reduces their lifespan. Refer to the specifications for your fan, which indicate a higher maximum voltage than the rated value.
