High temps on new loop "PROBLEM SOLVED" - Page 2

It has a molex connector for power and 1 blue wire on a 3 pin plug for RPM

I think I,m going to need to do this also, there is a bunch of heat coming out of the end of my cards and its heating the hoses.

I did change the fans on the rad to push toward the case and the temps went down 1-2c but its still not enough.

Any suggestions what to use to clean the copper block with when I try reseating it?

Your pump's definitely moving water, or you'd be getting much higher temps than that. If you can see movement in the res, I'd say flow isn't your problem. There's a chance it's a bad mount, but TBH mounting a block isn't that hard and I doubt you've done it wrong several times in a row.

Off the top of my head, it could be bubbles in your loop, gunk in your CPU block, or hot air across your rad. (Or maybe you've got your inlet and outlet mixed up on the CPU block?)

It does look like your GPU exhausts are dumping right into the bottom half of your rad, maybe try repositioning it for a test run before you drain it?

All I know is I was getting slightly better temps with an H50 and all my cores were very close to the same temp, now they are 5c apart from low to high.

I definitely have the hose coming from the rad to the "in" on the block but it is upside down, not sure if that matters or not.

I put 4 fans on the rad, its pushing and pulling towards the case so Its not sucking hot air in from the GPUs

I took the drain line off because the plastic tee cracked and had a small leak, so when it was apart I blew into it and it was really hard to blow the water through but I could do it.

I have rolled the case end over end and laid it on it on its side to try and get the bubbles out and they still form just outside the block outlet about the size of a large Pea for the last 4 days......

I don't like pea sized bubbles though... I've heard that a single drop of dish soap in your loop will help clear them out. If that bubble won't come out, that's got me back to thinking that you've got a restriction in your loop which is limiting your flow. Ordinarily your pump should be able to push those bubbles through to your res, especially with an unrestrictive loop like yours. That's supported by the difficulty in blowing through it, and I think it might cause your uneven core temps too, if you've got a persistent bubble in the right spot.

If it were my build, at this point I think I'd just drain it, take everything apart, and check components. Take apart the CPU block and clean it, rinse your rad out really well and blow through it to check for obstruction, and test your pump with a couple buckets of water. (I'm sure you know not to run it dry, use some extra tube between a full bucket and an empty one, suck on the drain hose until water reaches the pump and primes it.) You can figure your flow rate with a stopwatch and a little math, compare it to the advertised zero resistance flow rate (don't know it off the top of my head.)

If that doesn't fix it, consider me baffled. Sorry!

Actually, wait. Another thing that might cause that would be having your inlet and outlet backwards on your pump/res. Check that first before you tear everything apart.

When I blew through the system it was full of water thats probably why it was hard to blow, I'm gonna try the drop of dish soap, but I think I will take your advice and take it all apart and check everything this weekend, it really urks me that its not working well...

It doesn't take a lot of bend for some hose. I have MasterKleer 3/8" PVC and I put several clamps on tight spots to force the tubing to open. Hope this helps....good luck!

The hoses are fine I dont have any tight bends, but thanks

I think I may have found my problem, I bought this cooling system used, the person I got it from must have taken the block apart and put it together wrong.......in this pic the small groves in the copper plate are crossing the metal pate, when I took it apart the grooves in the copper were going the other direction and I could hardly blow through it, now that I changed the direction I can blow through it freely ...

now to reassemble and see what happens.....fingers crossed!!!

Well I'm STOKED! Even with ambient temps of 88*f my cores are at 68c while folding, and I only have 2 fans on in the pull position, thats a 20c improvement and the weather is 10*f hotter!

Also the air bubbles that were forming before are not forming now..... its a beautiful thing ....
