Hi
I took delivery of a custom OCUK pc a few days ago and I’m having issues with the CPU overheating and was hoping for some advice as their not open until Monday.

In the bios it’s running at +80c and on start up it reaches +100c without anything unnecessary running and eventually just shuts itself down.

To the best of my knowledge I’ve updated everything I need to.
I’m not overly tech savvy when it comes to this so any help would be appreciated.
I’ve attached some pics of my spec, fan bios and fan info when started up.

Thankyou

what cpu and cpu cooler do you have?
have you checked the fans are spinning?
if AIO, have you checked the pump is pumping?
have you checked the fan connections haven't come loose in shipping?
have you checked for other shipping damage?
 
on the face of it, it's probably how the cooling solution is fixed to the cpu and the associated fans. No CS on Saturday?

Deepcool LS720
All fans are spinning and all connections as far as I can see are fine and can’t see any other damage.

All cables are connected.

Can feel some kind of movement, but very slight.

I wonder if they forgot to remove the protective cover on the waterblock, if your comfortable you could remove it and see but if it's under warranty maybe best left until you contact them.

GO into the bios and look for pump speed we what it's at , you could increase it if low see if that helps.

Just checked the fans in your cooler have max rpm 2250 pump is 3100.

Oh ok. I did ask OCUK in my order email to check everything was ok together.

What would be the fix for this please?
Thanks.
 
Wouldn't OCUK bench test new builds?
If so it sounds like something has come loose in transit.
The pump block on this aio doesn't have plastic film, it has a plastic cover that has to be removed before you can install.

I've just checked the installation guide and there is no cover than needs to be peeled off the waterblock , so that rules that out.

Check the screws on the waterblock are not loose.

In the Gigabyte fan control centre at time of posting it says:
CPU 2296 rpm
System 1 - 4383 rpm
System 2 - 741 rpm
System 3 - 0 rpm
CPU OPT - 0 rpm

Is this all normal?

Also, I just selected full speed option and it brought it from 107c to 38c but obviously I don’t want my fans at full speed on zero workload.

Can you follow the cable from the pump and see which header it it plugged into on the motherboard, normally there is an AIO pump header, failing that I would put it into the CPU OPT header.

System 1 is probably the pump speed

CPU is the fans for you cooler

System 2 suspect is case fan.

But check cables.

You need to set a fan curve or set an auto/optimal setting so the fans speed up as temps rises.

Unfortunately I don't have any knowledge of your motherboard software so you may have to play around or somewhere here mite be able to help.

Cpu_fan and sys fan1 both are both connected.
Cpu_opt is empty

Thanks.
I’ve already tried the different pre sets they give and I’ve also used a similar guide you linked as well but didn’t help.

They could just be fans plugged into those ports, can you follow the wire thats coming out of the pump and see where it goes.

The manual for your motherboard actually states to use CPU-OPT or SYS FAN 3 for the pump lol, guess they didnt read it

1 of the cables from the pump goes to sys_fan 1.
The other cable from the pump goes to a loose connector/splitter and then back to the 3 top case fans and not the aio fans.
The connection from cpu_fan goes to the aio grill.
