PC Chilling (laser project)

[Andy_con]

i need to cool something that generates 300w of heat, is there some kind of computer setup that might do such a thing?

i know nothing about computer chilling setups sorry.

Yes, there should be plenty of options, the main potential difficulty is in mounting the cooler to what you want to cool and getting good thermal contact.

Is it something which could be immersed in water? Or something non-conducive like mineral oil?

given i have a cnc mill, im hoping mounting wouldnt be an issue. i can machine what ever i need

its a laser diode so cannot get wet

A 280mm or 360mm AIO liquid cooler would be able to handle 300W, assuming you can attach it somehow

are you referring to something like this?

Yup those, or a Corsair H100 or similar. Generally fed by power, ground, pwm signal and often have a speed sense output.

Yep, something along those lines should do the job just fine.

You can now get air coolers which can handle 300W loads too, but they’ll be on their limit. A decent water cooling loop should handle that load with headroom to spare.

Really it depends what your future plans are, if you think you are going to need to add more components in future then I’d go with a custom water cooling loop for the flexibility and ability to easily add more cooling in future. It will be more expensive though so if you’re just looking to try something out then an AIO is a good shout.

do they NEED a pwm signal?

do they NEED a pwm signal?

I’m not sure tbh, I’ve never tried. Basic fans will just run on 12v but I think the pump might not?

ok, something i may have to deal with then.

 

[charltjr]

It depends on the pump, you’d need to check the specific AIO. That said, you can pick up manually controlled 12v PWM signal generators for less than a tenner on eBay, or Noctua do one for about £20 if you want a trusted brand.

Don't you want a liquid cooled diode mount?

Like this, but bigger?

Whilst I love thorlabs, they sell the stuff dreams are made of. I cannot afford their equipment.

DragonFire: UK laser could be used against Russian drones on Ukraine front line

The defence secretary said the laser could be used to take down Russian drones as early as 2027.

This what you're needing to cool?

na thats just a toy, mine is way more powerful
