Nope, I have a pair of 120mm rads. Specifically 120mm x 28mm, so they're on the thin side (otherwise only one fits). Behold my house of poor choices!

As far as "doing well," keeping a 320W GPU under 70C in a lovely case is already asking a fair amount from 240mm worth of rads. Throwing another 50-75W of CPU in there with a X570 chipset and some lights belching excess heat (why the hell are the UV lights that hot?) and I'm actually very pleasantly surprised.

I'll run the tests here in a few and get back to you two, but I'm not sure what you're looking for out of them: I'm pumping 300-400W of heat into a system with no effective res in a case well known for lovely airflow, and while 2x120 rads are keeping things below thermal limiting break points, they're obviously undersized for the task at hand (at least in the sense that everyone going into watercooling seems to obsess over keeping temps ultra low--this setup actually ends up being considerably quieter and cooler than the air setup beforehand, and they're no longer thermally limited, so in that sense the rads could be argued to be viably, if not optimally, sized for this).

It's mostly me being really curious as to why the CPU is reading so hot. But enough about that.

Make sure you check the o-ring!

But yeah, Zen3 just runs hot. 7nm means silly high heat density, so even with very good cooling it's not unusual to see higher temp readings than you'd expect--even if the coolant isn't warming up all that much; it's just harder to get the heat out of the die in the first place than with previous generations. Even open-air test benches with good coolers are seeing stuff like ~40C idle temps and loads in the 70C range.

e; There's some churn that this might be because AMD right now has set very aggressive power profiles and are over-volting the chips considerably, but my motherboard / chip / BIOS combo right now means that even a -1 offset with PBO2 immediately makes it unstable, so I'll have to re-attack undervolting later.

You should have warmer water and hotter component temps, but the water should still be consistent anywhere in the loop.

Input and output on which component(s) got switched? CPU blocks tend to be sensitive to in/out, but that's an extreme difference for just that change.

Input/Output for the CPU block / pump / res combo. Basically it's running backwards now. So before it was Res/Pump/CPU -> Rad -> Rad -> GPU -> Res/Pump/CPU, now it's Res/Pump/CPU <- Rad <- Rad <- GPU <- Res/Pump/CPU.

I think the high heat generation (~400W), low liquid volume, and low rad surface combines to exaggerate the impacts of ordering more than you'd see in a normal setup.

Since they don't actually have a sensor on the fluid temp, we don't actually know that the fluid has a significant temp, only an anecdote that there was an observed temperature difference between the components, which we don't have reliable testing data for.

It's still just so improbable it defies belief, given how many controlled tests out there show that order doesn't matter (and flow rate has very minor impact outside of edge case low flow situations). Even your 'extreme' scenario is no more than you doing stupid things with an Eisbaer + Eiswolf pseudo-AIO, which I would never hypothesize these results for. But I'm obsessive enough about this that if I had your system I'd have already bought a coolant sensor and done those tests I recommended on both configurations because I wouldn't be able to sleep until I could explain the behavior

The only thing that matters is taking note of jet plates on blocks, such as a CPU block. Water should be IN to the jet plate and OUT of the other port. These are usually labeled.

Otherwise you aren't going to see a difference.

Ah goddamnit.

Most cases are made for AIOs. As it seems. That or you need to put a watercooler on the graphics card, too.

Here I am buying parts for a water loop for whenever AMD starts making CPUs again.

I've already got the pump/block/rad that I wanted; nothing fancy. Is there a general consensus on where to go for everyday fittings, tubes, and those fiddly parts? Kind of like monoprice, but for water stuff, is what I could use recs on. Thanks.

Rebuilt my system. New CPU/GPU/Motherboard. Case and loop stay the same. Ran overnight leak test, everything checks out good. Reboot system and start formatting drives to reinstall windows and start fresh. System hangs, blue screens. Then that burning plastic smell we all dread. Oh no what did I do?

I didn't notice that the pump wasn't running. The CPU was overheating, the water block on it was hot to the touch.

The good news is that the smell seems to have come from the pump itself. I guess it just chose this exact moment to burn itself out. I tried hooking it up to different power connectors, even an old PSU. No dice.

I hope nothing else got fried, but I'm going to have to wait a week and a half to find out. I head out of town Tuesday morning and the local Microcenter doesn't have squat for pumps.

I think all new CPU's have very good shutdown protection so it's probably fine.

Pump failure is one of the reasons I went with dual pumps, with a flow sensor to an Aquaero 6 to let me know / shut the system down if there's no flow.

Normally pump RPM dropping to zero would cause an alert.

If, you know, that software wasn't in the process of being wiped from the drive.

I'm building out a new pc and picked a bad time to do it because AMD does't produce CPUs anymore.; however, this has given me a lot of time to buy all the other poo poo, including a big fuckoff water system I've always wanted to do.

I have no idea what I'm doing, but I'm buying pumps, radiators, blocks and tubing. I work out of my garage and have always just had my working pc siting out here with me, bare, without a case. No plans on changing that, so I'm not limited in size/scope. Oh, I'll make some sort of wooden tray/frame to hold it all, but the innards will mostly be exposed. It's super fun and there's a ton of possibilities.

I just bought something that looks like a giant bong. I'm told this is a D5 pump with 400ml reservoir, but whatever it is, it's pretty big.

It's doing this kind of stuff that's been keeping me sane (I think).

Half the fun of my current build is that I have no idea what I'm doing. Sure I'm going to end up with a handful of left over unused fittings because I don't know what I need. Plus I decided 90 degree fittings look better than 45 degree ones. Then changed my mind about PETG and changed to acrylic because it cuts much better. Then changed my pumps from the kind with a speed dial on them to software controlled pwm pumps, and changed from Corsair LED's to Aquacomputer LED's because I hate Corsair's LED control software and I'll probably change things still before the build is done but it's a continuous flowing process.

I'm currently trying to decide if I should get a second small power supply (Corsair SF450) dedicated to powering the pumps just so it makes filling the loop easier as once all the tubes are in, it's going to be a pain to plug all the cables into the motherboard and gpu.

I also just brought a 24 pin + internal usb 3.0 90 degree adapters, and they look so much better than the cables sticking up vertically and having to do a 180 in the air. Might try and get some for the dual 8 pin EPS my motherboard uses, plus some 8 pin PCIE 180 degree ones.

Which tube? The one on the left is bottom rad straight up to top rad, I was surprised I only needed a 90 into a 90 fitting for that.

What amazes me is the gpu fitting is perfectly in the same axis as the reservoir. Just a 90 going right to meet the reservoir going up.

I did consider doing a GPU CPU Parrallel line setup but they didn't line up so


Next bit to do is the flow meter to radiator. Can't really do any more until my spacers arrive for the rad > cpu fitting.
