Removing barbs. Any problems?

I was considering putting a dangerden Maze4 Northbridge cooler into the GPU loop to allow for more cooling on the cpu. The GPU loop I am making is 3/8". I have a 1/2" maze 4 chipset block and wondring if anyone knows if its ok to unscrew the barbs and replace them with 3/8" barbs?
 
just out of curiosity...what type of system are you running? If it is athlon64 you dont need to watercool the chipset at all.

As to removing the barbs, I am not sure, but I dont think replacing them would be a problem, just make sure you use some sealer on the new barbs to make sure it wont leak.
 
most of the maze blockes have the barbs epoxied on so you have to break the seal on that if you have the lucite tops there is a chance of cracking the top

I replaced the barbs on my Maze4 cpu block no problem just put some silicone on the new threads to seal it up. I don't like to use teflon tape as it puts more stress on the lucite and can cause it to crack.

Just a note - your lucite is already cracked from being machined. This is why I won't buy a block with a plastic lid. Most polymer materials used for this application are succeptible to crack propagation for seemingly no reason. They exist from the time the threads were cut, and can grow due to thermal cycling, vibration or fatigue, chemical alteration, or other reasons.

ronenvelarde - there is no inherent problem with changing the barbs, just be careful of how you treat the threads and be sure to seal them when you put the new barbs in.
 
I purchased a DTek Spiral waterblock from a board member.

It originally came with 3/8"
he removed them and put in 1/2" plastic using epoxy.

Last night, when I got it, I had to drill out the plastic barbs. Lucky for me, the original threads were still good. I went to HD, got some brass 3/8" barbs, put a little silicone on them, screwed them in, and let it sit.

Tonight I shall test the system for leaks, then install.
 
ehh, Might be easier and less risky to just buy another block. What I did was buy 3 blocks all 1/2". Now im considering putting the cpu on its own loop with a BI PRO Dual rad and then putting the GPU and N/B on its own 3/8" loop. The GPU waterblock would be one that covers the ram also and I havent been able to find one 1/2". Or I could just leave the CPU and N/B together but they build up a massive amount of heat. Socket T prescott. x800se pcx card. Put the GPU on its own loop. I have a BI PRO Single rad for the 3/8" loop.
