Which adhesives for GPU waterblock?

Recommended Posts

I've gotten mod crazy this week. All my pent up neediness for the last 10 years have come out in a slew of ridiculous mods.

 

I am now attempting something dangerous: turning my GPU air cooler into fins for a water block. I'm building an acrylic encasement that will be sealed in between the individual fins of the heatsink, with channels to ensure it utilizes all possible surface space.

 

I have only one question:

 

Which type of adhesive is best to seal the acrylic with? It must meet several conditions:

 

1- it must be waterproof.

2- it must be able to bond to metal and acrylic, particularly on smooth surfaces.

3- it must be able to tolerate heat, as this Is acrylic water block.

4- it must be viscous enough to apply with precision: I'm basically using a can of old brushes from painting ceramics for the finer areas here.

 

Before I finish, I am fully aware of all the dangers. Yes, I am new to custom PC mods, with only experience doing minor things involving little to no fabrication. But I have almost 20 years of experience with fabrication in areas other than computing. In the end, if I fry my PC it is my fault and mine alone. I'm fine with that. I'm modding it instead of using it because I find the work highly enjoyable.

 

So, anyone know of a good adhesive for this job? I have the entire thing laid out and ready, just don't want to waste all these cuts by using the wrong glue.

 

Thanks In advance. Will post video of the project if all goes well.

Sorry for bump, not sure how to edit post on mobile. In case you're curious, I cut the acrylic to precision with a heatgun. I got the heatsink hot as hell and just pushed the acrylic into the heatsink. It cut a thousand little sheets perfectly. Dipped it in a bucket of ice water and the acrylic popped right out of the fins, no residue whatsoever.

Nice trick to save days of cutting.

Hello Gunny, looks like an interesting project.

 

When bonding acrylic you want to use acrylic cement, which does not contain any adhesive the cement bonds the acrylic together kinda like welding.

First, I'd like to thank you for your response, however this won't fit the bill. Video to explain a little better what I need and why:

My best advice would be going with Asus Poseidon https://www.asus.com/us/Graphics-Cards/POSEIDON-GTX980TI-P-6GD5/  and EK-XLC Predator 240 (AIO).  

This is more about wanting to do something exciting than the efficiency.

 

I have an AIO for my CPU (Captain 240). But for my GPU, seeing as I'm upgrading it next month, I'd like this to be an "experiment" to satisfy my own curiosity of the possibility and efficacy of the project, as well I'm sure some people on YouTube would like to know if this is even remotely feasible.

 

I'm doing this for fun really.
