Replacing laptop fans for more performance?

I'd say a thermal repaste and undervolting are your best bet. Your laptop was designed for those fans, so I wouldn't risk any chances.

    • Yes, thats not how cooling works(more rpm = more cooling)

    • No, you should capitalise this idea asap.

Hello people,

 

So im a long time watcher of the LTT youtube channel finally thought aboutnmaking an account when i was thinking about something.

 

So laptop fans surely there is difference in fan quality across the board. My question or thought was: is it possible to change out the stock laptop fan for a better one ( supports faster rpm since you cant really get a bigger one fitting since laptops are made to spec).

 

Hereby id like to employ the great minds from the LTT forums what are your thoughts? Is it plainly a stupid idea or do you see potential since i beleve they do all use a standart fan pinout.

 

In the end the thought came up because i have a lenovo legion y720 with a gtx 1060 6gb with a i7 7700HQ. I was doing regular maintenance ( cleaning the gummed fans) when i was done i was running it at max fan speed without the bottom lid got 24c idle temps even tho noisy i dont mind.

I don't think it's worth it, I've never thought of changing the fans in my laptop, or desktop for that matter, simply because it doesn't seem very practical.

 

All my computers roast like the sun though :/

The fan headers are built into spec as welll, you might ruin something with higher wattage fans as it draws too much current.

 

If your laptop gets hot, undervolt the CPU.

And what makes you believe that? :P

 

On the other hand - I kinda doubt you are going to get much better thermals there. There's not much difference in such slim fans anyway.

As the conclution i suppose undervolting and reaplying thermal paste is the way to go cheers mates.
