Hot cpu Noooo

I added another radiator and gpu block yesterday. Now my cpu idles at 50 instead of 25, and hits 65+ with any workload.

I'm hoping I just need to turn up the pump ( need a longer screwdriver to access it). I'm also thinking maybe the cpu block isn't tight enough?

Any other thoughts?

That took me 5 hours yesterday, I really don't want to drain it :anguished:.

Yea the GPU is gonna add a good bit of heat to the loop but you're still well within regular operating temps so no need to worry. CPU block just needs to be snug, dont over-tighten it. Turning up the pump can help a bit but I wouldn't go past 90% for the sake of its lifespan.

The pump should be fine to handle that setup. Try turning it up like you say.

Don't overtighten the cpu block, that will cause more trouble than it fixes.

Did you tip the case from side to side to get rid of trapped air?

No it's definitely wrong, it was idling at 32 on air. Amd 1700, I've had at at 3.85 1.4v on air running a stress test for 3 hours and it didn't reach 70.

@mora, soooo much tipping. There's one small air bubble left in the res at the opposite end to the out.

It's really looking like I messed the cpu block up somehow. I'm gutted.

What speed is the pump running at?

Atm setting 3 of 5 (alphacool Eispump) just on molex. I can't get a small enough screwdriver to turn it so I'm just going to man up and .disassemble.

A 25 to 50C jump rather hints at some mechanical f-up.
I'd go check the block mount and piping to make sure.
There's just something wrong there, particularly with a second radiator.

Then again a second radiator requires more pressure for your loop, might need to check if your pump is rated for that

Bumped it up to max pump no difference, I messed up putting the cpu block back on it looks like. Hopefully, because that's what I'm starting to fix now.

The pump should be able to handle it, I picked X-Flow rads because they're alot less restricting. My cpu block is pretty restrictive though, hopefully it's not that. Not sure about the gpu block.

Thank god I bothered to put a drain value on the bottom.

Yep, check the mounting of the CPU block, that is going to be your culprit.

I'm running 2 360mm rads, CPU, full cover GPU, chipset, and VRM blocks with a D5 pump and dual bay res. I run my pump at 40%.
Increasing pump speed is for overcoming restriction in the loop.

It's really annoying, I only redid the cpu block to change the thermal compound for better.

I know I had trouble with my GPU block when I installed my gtx980. I can be a challenge to get them to seat correctly. Oh the joys of water cooling! I feel your pain.

Thats because the air cooler only had to worry about the CPU.....

I have a 4790k and 2 R9 390s (non-X) in my loop with 3 rads, 360mm, 280mm and 140mm and my CPU idles at 45c and gets up to 70 under load. Its really not a problem dude.

Trust me it was wrong, 1700 is very cool.

Well I redid it, the cpu block seemed to be seated correctly, swapped the noctua Tim for phanteks and the cpu is at 28, gpu 42 playing witcher 3 at 4k.

Ive set the pump to max, when a screwdriver gets delivered I'll be able to see if the pump was the issue.

1700 is one ice cold baby.

I don't want to touch it for another year!

Well I found the problem. Dodgy molex connector. Or dodgy pump.

It didn't start when I came back from the weekend. Had to mess with the connector a few times. I didn't notice the first time because it's normally quiet on 3 and the fans span up fast.
