Question Ryzen 5900X cooling - - - too much heat ?

[StaalZA]

Howdy,

So I changed my chip from a 3500X to a 5900X on an updated https://www.gigabyte.com/Motherboard/B550-AORUS-ELITE-V2-rev-10-11. My case was the Corsair 4000D Airflow. As time progressed the old 240mm Antec Kukler seemed to be battling a bit to cool the 5900X once summer started. I then did a bit of research and decided to change the case to a new Antec C8 ARGB and an ID-Cooling SL360 XE Black Space. The Antec C8 Case (new) has some serious airflow with it's 2 x 160mm intake fans at the bottom, 1x 120mm extractor at the back and the 3 extractors at the top with the AIO. The AIO was mounted at the top of the case.

Starting up the machine, the CPU temps easily goes to 80+degrees at idle and peaks at 90 when I do something lite, like browsing.

I repasted the cooler, tested the mobo headers by swapping the radiator fan to the Mobo CPU_OPT and the pump header to CPU_FAN. In both cases the radiator fans spin, but there is no way for me to determine that the pump is pumping. In the bios, gigabyte command center and the ID-Cooling software the connectors show RPM but the cpu does not cool down.

Can the chip somehow become old/degrade and produce heat uncontrollably?
Could it be that the MOBO is not producing enough power to turn the pump?
Is it perhaps just a case of a faulty cooler?
Is the Cooler not up to par and worse that the the older, smaller Antec cooler?
Any idea how I can further troubleshoot this issue?

Dinky doodle case. 240mm cooler is too small. I built a rig with the 4000 case. Forget if a 360mm AIO will fit. The CPU_Opt is if you have a fan cooler + AIO. CPU plug stays unpopulated.
Mount the radiator where it will be most effective. Up top!

Hi Jeffrey,

Thank you for your reply. Not sure what a Dinky doodle case is.

Either way the AIO was mounted at the top.

In the motherboard manual point 5 (top of page 17) it states the CPU_OPT As being the Water Cooling CPU Fan Header.

Which of the CPU plugs should stay unpopulated? CPU_FAN & CPU_OPT are located together.

Where would you connect the AIO pump connector and where would you connect the radiator fan connector?

I am not familiar with your motherboard. Look at the motherboard layout. Usually the AIO and CPU_Opt are next to each other. You don't need CPU fan unless you are using it as a second fan. AIO connection is what you are looking for..
Dinky doodle case refers to a small mid-tower case with tons of junk inside. I like full towers. Far better at managing heat. Last build, Corsair 7000D. It is huge case. Really too big..

There is no alternative header but for CPU_FAN & CPU_OPT. I need to connect 2 connectors for the AIO to work. 1 connector for the AIO pump, one connector for the Radiator fans (3 fans daisy chained). Are you saying I should not connect the pump to CPU_OPT and the radiator fans to CPU_FAN?

Sorry it is labeled CPU_Opt is correct.
5) CPU_OPT (Water Cooling CPU Fan Header)
Please refer to the motherboard layout. Page 4.
Too early here!

Yeah, aware of the connectors. Like I mentioned. I have connected the radiator fans to the CPU_FAN header and the pump connector to CPU_OPT.

You suggested that the second header (either CPU_FAN or CPU_OPT) need to be unpopulated when using a AIO cooler. Now my question is, 1. do I connect the the pump to CPU_OPT (named Water Cooling CPU Fan Header in the manual) or CPU_FAN header? and 2. Where should I then connect the radiator fans?

CPU_OPT is used for the AIO.
Did you download the manual?

thanks, the pump has been connected to CPU_OPT from the start. So the connection is thus not the problem with the high heat unfortunately.

I gave you other suggestions. Every core in your new CPU generates heat. 2 years ago going from an AMD 5600x 6 core to an 16 core 5950x. 5950x runs 10c warmer. Going from a 3500x to an 5900x. Add a small case and inadequate 240mm AIO. What do you expect to happen?

The TDP rating on the cooler in question (360 ID-Cooling SL360 XE Black Space is more that sufficient at 350W. The 240 was referenced only as a test of the mobo headers after the 360 was not cooling at all. By no means is the old Antec 240 AIO the issue, nor is it in use. I stated that I "change the case to a new Antec C8 ARGB and an ID-Cooling SL360 XE Black Space." NEW COOLER: https://www.idcooling.com/product/detail?id=451&name=SL360 XE

Additionally, the Antec C8 is dual- chamber FULL case. https://www.antec.com/product/case/c8-argb https://gamersnexus.net/cases/surpr...b-case-review-thermals-cable-management-noise

What I 'expect to happen' is figure out why the cooler has NO effect on the temperature, not a few degrees warmer than expected,

I've not used an AIO of any sort but it's my understanding you should run the water pump at full speed all the time, i.e. permanent +12V. The radiator fans can be run at variable speed (as normal), depending on the CPU temperature. Hot CPU, faster radiator fan speed.

If your pump speed is going up and down, you may not be pushing enough water through the radiator, especially when the CPU idling, so your coolant temperatures may increase by a few degrees above optimum.

People with more experience can confirm or deny this theory, but I'd suggest checking the fan curves in the BIOS and set the pump header to run at full speed, regardless of the CPU's temperature.

With the pump running flat out, place an insulated sounding rod on the pump body and press the other end against your ear. You should hear the motor noise conducted through the rod. I'd use a plastic chop stick or a wooden dowel.

At least with big air coolers, I can see if the fans are spinning, but I expect a good 360/420mm AIO would allow my 7950X to boost slightly harder.
