1st time build...connecting AIO to ASUS mobo...

Hi all, I'm attempting to build a gaming PC for the first time and have connected everything up and installed an OS, however....

My CPU temp keeps rocketing up even in idle on the desktop. I have an ID Frostflow 240 cooler on an I5 processor. I've checked this out and removed and reapplied thermal paste (pretty sure it's not this).

One thing I'm unsure of is that I've hooked up the cooler properly. It's top mounted with the fans on exhaust. I've put both the fan cables into a single adapter and connected to the mobo. The pump cable is meant to go to SYS_PUMP header but my mobo - ASUS Prime B760M-A - does not have a header _PUMP.

It does have CPU OPT and CPU fan and I've tried putting the pump in CPU FAN and ignoring through BIOS but still can't stop the temp rising.
Also tried limiting the frequency through the CPU to take the strain off and that still does very little to stop the CPU temp rising rapidly. I must be missing something obvious but have v little experience. Any assistance greatly appreciated.

spilt the pump and the fans
fans to cpu fan
pump to cpu opt

this is usually either user error (ie you installed it incorrectly)
or
the aio pump is physically not working

as an aside, this is a classic case of a picture is worth a thousand words.
post a few pics of the computer innards, please
 
Thanks Tamzy. I tried the inputs per above previously but that didn't work unfortunately. Will take some pics tomorrow morning (it broke me today, 8 hours of teeth grinding )
 
Excuse the 'stupid' questions but:
Are the fans spinning?
If you touch the pump can you feel the vibrations from it working, you might even be able to hear the faint hum.
Have you got the right mount, screws and plastic tube/washers installed for the cpu socket you're using. You can have the right screw placements but the height is wrong due to the tubes/washers etc, this can be a pain with a bad manual.
When you took the pump off was the paste spread properly and I assume you've cleaned and used new paste when reattaching.

Side thoughts you might need to go into bios and change the settings for the cpu opt to 100% or even dc output for it to work properly (can't remember what I needed to do in my bios off the top of my head)

No worries mate, building a PC can be intensely frustrating if it doesn't work right off the bat lol

What CPU are you using with that mobo?


could you describe what didn't work? (or what happened?)

Morning Tamzy, a few drinks and few hours sleep and I'm ready to break myself trying again!

I'm using (attempting to use ..) :

Mobo : ASUS Prime B760M-A Wifi D4 (LGA1700)
CPU : Intel i5 12400F
GPU : AS Rock AMD Radeon RX 6600 Challenger
AIO : ID Cooling Dashflow 240
PSU : Corsair RM750e
RAM : 2 x 16g Corsair Vengeance
SSD : 1tb

When I said didn't work yesterday I meant when in the desktop with nothing apart from a piece of monitoring software running, the CPU temp steadily rose from high 30'sC up to 80c where I turned off.

LSG, thanks for responding and very happy for you to assume I'm a dummy (it's my first time trying to build so technically I am. Please see examples of this further down..)

Fans are spinning and lights are on the cooling unit

I can feel a faint vibration

I checked the instructions for the right mobo mount (at least 3 times) and looks mounted correctly

When I removed pump the first time yesterday I had made the idiot mistake of not removing the sticker on the cooler plate...I then cleaned and reapplied thermal paste.

I then checked it again later in the day to make sure the spread was even and it was, I then cleaned and reapplied again before putting back in place. I now have no thermal paste left.

Did the cooler come with a SATA power adaptor for the pump?

Install video may help.

Thanks Freddie, see post above, I had previously made the ridiculous mistake of not removing the sticker but fixed earlier in the process yesterday.

I do have a SATA adapter BUT the pump cable from the AIO has 3 holes but the adapter that feeds to the PSU only has 2 pins so I tried putting the pump power direct to the mobo using CPU_OPT header.

I'll add pictures of the build so far plus the cables to hopefully make my description easier to follow.

Sorry but I don't know how to add photos to the post! Any advice on this would be appreciated too

Photos you first have to upload them to a hosting website like lmgur then you can link them here and we can follow the link . Posting them here so we see them you press the 3 dots in the centre a few options will appear 3rd option from the left is video ans picture press that then post the link therel

Post reply and pic should appear.

For trouble shooting keep it simple...
Use the sata power header.
Boot into bios and put all fans to 100% and see if this does anything

SATA power will be 2 wires as it will run full speed all the time.

Looking at your photos, you may be best remounting the pump so the tubes are next to the RAM.

The way you have it, waterflow is going across the CPU and not cooling efficiently. (that's my thinking and i may be wrong)

Oh and i forgot to remove the sticker on my Arctic. :o:D

May be look into undervolting the CPU as that will reduce temps as well.
 
I don't know what the cause from improper installation here is, but my 2c anyway:

The fact that the cpu starts at 30c at idle and then rises to 80c at idle is very telling. This high temp and unmanaged rise means no heat is dissipated through the radiator or block.

Here are some causes for these temps:

* Pump is not spinning - pump may be dead or is not receiving power

* Sticker on the base plate

* No thermal paste applied

* Incorrect mounting of the block

* Fans not spinning



With the PC at idle, try to put your ear near the block and listen for pump noise - all pumps make noises, you should hear the motor and also hear noises of bubbles - if you do not, pump is not spinning and is dead or has no power

I thought CPU opt ran same speed as CPU fan, in effect a built in splitter.

Not sure but it's worth checking.

Just googled to clarify and quote

Can I plug the pump into CPU OPT?

Yes, you can plug a pump like AIO into CPU OPT, though it is not recommended. CPU OPT is a special connection for the motherboard to keep the CPU cool at all times. So, it is better to use CPU OPT only for fans. If you connect the AIO Cooler to CPU OPT, ensure that the radiator is connected to CPU FAN.

Stop guessing and check your motherboard's manual, I can 100% gaurantee you the manual will tell you which port should be used to power your AIO. Should never be guessing when working with power, this is how PC parts get killed when you connect them to the wrong port
