Unstable temps + skyrocketing

Hardware Hub Cooling
1

I got everything up and running around 5pm yesterday. God the cam software installed, installed a few games and staple software then as I'm beginning to start to enjoy my new rig the whole thing resets due to a forced shutdown by the mobo.

Turns out it overheated. In a matter of seconds the CPU (kabylake) jumped from 28 idle to 100. Mobo shit a chicken and shut down everything.

I'm using the Kraken x62 and the fans are spinning. The tubes are humming so I assume the water is moving, but I can't be sure since I've never had an aio before.

I used real temp to check my core temps and it only confirmed the cam software. Shit was hot. I shut it down and haven't powered it on anymore until I have time to figure it out and change a few things.

I used the pea method for the thermal paste... Idk what it could be.

The only thing I could think of is that my cooler is not sitting on the CPU properly because when I was putting the standoffs I noticed 2 of the Intel chip 115x ones weren't screwing into the back bracket all the way. I worried this would be an issue but I tamed those fears thinking the thumb screws would help tighten everything properly. Now I'm REALLY worried.

Any ideas, fellow tech people?

Should try reseating the pumpblock. Something there seems wrong.

The cooler probably does not make contact at all. Otherwise it would never jump to max temp and shut off in idle. Even just the block should be enough to not let that happen.

Alright, so I'm convinced that the cooler is the problem. What to do to fix the standoff issue. 2 of them won't screw in all the way. Which makes me afraid of either breaking the back bracket or the mobo

What everyone has said so far about checking for cooler contact sounds right. That is the direction I would go in.

Even without any water flowing, it would take a long time for the CPU temp to go to max. Might be a fun test!?

Can you offer any advice about the standoffs. Two on the left of the CPU are not screwing into the back bracket all the way. If it's a CPU COOLER seating issue this is almost definitely the reason behind it all.

I would disassemble the cooler and the backplate. Then check the standoff fitment outside of the case. The threads on the standoffs or in the backplate may be damaged.

If they are damaged, you have a few options. Rethread the holes and standoffs or try to force them in. If you decide to force them, keep in mind that they are most likely going to be damaged or destroyed in the process. There is no guarantee that it will work either. Or, call the manufacturer and see if they will RMA or send replacement parts.

How to retread? Sounds like the way to go.

what voltage is your motherboard pumping @ stock? this is apparently highly variable between vendors on z1/270 and can have far more effect on temps than you'd think

10

Ah I did not know this. I'll have to check when I get home from work.

11

With a tap. The question is: Which size and metric or imperial?

If you have a mechanic or a car guy in your circle of friends you could go with backplate and stand-offs to him.

Honestly: I'd just contact the vendor or manufacturer of your cooler for RMA.

Actually with very careful, slow but strong force, I managed to squeeze it down fairly well. No cracking sounds or squeaking of any sort. I got lucky tbh. Temps are much better now. I realized my mobo is doing like a variable over clock. Where it clocks up and back down as it needs. Yesterday I was gaming at 4950 mhz. Which was cool and all and the temps were okay but I'd rather learn a way to scale it back to 4.8-4.7.

This. My gigashit Z170 gayming3 board was putting 1.35v to my 7700k stock. I was seeing 85c under load with my h100i gtx.

Also, you might seriously consider delidding.

I've been considering delidding since I first considered kaby lake.

I'm really scared to do it. As a family man, ruining a 300$ processor would mean not having a pc for months.

15

I can understand that. I would recommend using a delid tool that rotates the IHS instead of pushing it. I'm going to give it a go when I finally find a decent tool at a price I'm willing to pay, so when I do I'll let you know.
