Older watercooling any issues with converting it to AM4.

[Iceni]

Hey I've got an older EKWB setup that was designed before AM4. It doesn't have an AM4 mounting solution, and no conversion was ever designed for it.

I've modded it to work with AM4 and the Ryzen 3600. I don't however have a reference point for the temps so I'm a little unsure if the block is up to the challenge. The rest of the gear should be.

It's the EKWB HF240 H30 Kits.

DCP 4.0 pump
240mm copper radiator (thick style)
And the older style res.

The block is the Supreme HF CU/Plexi.

Idle on the block is 38-42C It bounces a fair bit on the Ryzen master software.

Loaded it's between 65 and 75 depending on the task.

The radiator is functioning well and feels cold on the exit side even after a few hours ,I have the pump set to 100% all the time (it's only 25db at full speed).

Would I see a significant improvement with a newer block design, and if so what should I be looking at.

I converted the block mounts with a milling machine. Cutting new holes where they should be for AM4 and hammering them a little just because of a lack of material to make the final push outwards for the mount. If there are no issues here I may cut the mount and re-do the mount points with some fresh steel welded and drilled just to make it more finished.

I think with a dedicated AM4 mount and a new block, you should see better temps but probably nothing major. The 3600 is only a 65 watt TDP chip at stock speeds and voltage. If you are overclocking, the new block would yield better performance all day long IMO...

What are your ambient temps? That's the biggest factor in determining if the mount/block are effective.

I don't have a thermometer to check locally.

I'm estimating +15c on idle. I did a clean and rebuild of it yesterday and it's dropped to 35-40 idle.

I also ran sins of a solar empire all day yesterday, Running a large advent bomber fleet (150 bombers in fleet and 90 planets all capped with bomber spam). It's a pretty good test for temps and I didn't get it to crash for a start, and the temps were sat at 65-75C after about 8 hours. Note that is CPU temp not cold coolant temp. The radiator on the exit side even after 8 hours was still cool.


Am I right in thinking the temps on Ryzen 3K are not true output readings. Rather a true reading then an estimate, and it bounces between the 2. Using some sort of algorithm to try and predict how much cooling is needed, rather than just working on raw information.

Update -

Crisis over. Realised my Motherboard was undervolting the pump. Popped in a Sata to fan adapter and the temps have dropped significantly.

Idle 26-28.
Cinebench R20 multicore 60.

Well in spec now.

I've opened a thread up on the MSI forum to see if that goes anywhere as it may be a bigger issues if AIO's on these motherboards are also undervolting.

For reference I have CPU_PWR1 (8 pin) installed. CPU_PWR2 (4 pin) is not installed and may be the cause of the issue.

I'll do some testing if I get chance over the weekend.

I was going to say "watch your motherboard's VRM temps" but you appear to have picked a processor that is unlikely to ever draw more than 100W and an overkill board with enough VRM and cooling to handle an overclocked Carolina Reaper 9000.

It was one of the cheaper motherboards that had all the features I wanted. The VRM is actually regarded as pretty weak for X570, but if you not overclocking then who cares! VRM heatsink does warm up a little but nothing that I'd be worried about, I mean I doubt I'm using half it's rated capacity!

The EKWB kit is something I've had for several years. It's been a very good unit. And those DCP 4.0 pumps are utterly mental at full voltage. If you don't care what it looks like you can't go wrong with them. Phobya still sell the same unit branded as the DC 12-400 PWM. If you wanted to do a custom loop on a budget it'd be the first thing I'd pick up, as it's powerful enough so as not to care where in the system you put it (4 meter water pressure head lol).
