For Science!

Really hard to say unfortunately. I also would say that LM on GPU waterblocks yields very little gains and the risk is not worth it.

Instead of going through the hassle of reversing the fans, just remove all the side panels and see what difference it makes.

Assuming you have it as you say you have it (as I cannot verify from the photos) then yes, you have a push-pull configuration correctly set up for an exhausting AIO, which is in my opinion the correct way to set it up. Your other fans are also fine in my opinion, although inevitably people will let you know that you have a net negative pressure assuming all the fans contribute to flow equally (which they don't). So you may want to slow down your top exhaust to balance the pressure a little bit but don't let it bother you too much.

I guess then your options are limited: 1. Find out the fluid temperature to ensure you are somewhere reasonable (around 40-45 would be my expectation) 2. Confirm the fins of the CPU block aren't completely clogged or something of that nature 3. Try to unmount the radiators from the case, and put the fans in push, and then run the system but with the radiators outside the case 4. Check your CPU voltages, maybe you are overvolted for the stock clock. (i.e. the motherboard defaults are not good).

Firstly with respect to noise. The fans look poorly optimized for radiator use, so changing them out in the long run will likely improve cooling as well as noise. Additionally, fans in pull configuration usually produce more audible noise especially up against a heatsink or radiator, so putting that in push-configuration may help with the noise profile. Of course, at the cost of making it easier to trap dust inbetween the radiator, but honestly, its not a big of a deal as some make it out to be. With respect to temperatures. The only major driving factor imo is going to be the mouting pressure. Make sure you screw down on the block sufficiently, and ideally confirm it by making sure all the thermal paste is squeezed out so that you have maximal metal-to-metal contact. Other factors such as pump speed and flow will have very little impact on the cooling performance.

Give or take, yes, everything seems to be about right imo. GPUs dump a lot of heat into the system so the increase in CPU temps seem about right to me. Probably about 5~7 degree increase in fluid temperature. Adding a bigger reservoir will only slow down the rate at which it reaches the same temperature from a cold boot, and also extend the time it takes to cool down after a load. It will not make the system any more efficient. Component order is fine, will not impact temperatures especially with a D5 at max speed.

Maybe finding a game with high replayability that you enjoy will at least allow you to use the computer and have an enjoyable experience - while not spending any money. For example, I enjoy playing Deathrun Modded Subnautica at the moment and can play days on end, and given that it isn't a triple A latest game, I can play it fine on my not latest PC.

I think they are just covering their rears. Admittedly, after filling a system and the air works around the system, I do open the reservoir to top up the sytem, and occasionally there is pressure buildup, but the process of topping up the reservoir (sometimes to 100% in my case) relieves the pressure. So I guess that's that.

I guess they read "pressure" and stopped thinking.

Assuming those two PCIe cables terminate into separate slots on the PSU side, then yes, you are no longer using a daisy-chained PCIe cable.

Maybe I'm being thick, but I thought PMMA is just the chemical name for acrylic. So yes, it will stand-in for acrylic, but acrylic should also be fine for shipping.

As a side note, I would also recommend plumbing in a 2-pin temperature sensor in the loop so that you can keep an eye on the fluid temperature. In fact on some motherboards such as Asus, you can tie the fan curve to the liquid temperature, which can prevent such mishaps and also yield an overall more quiet and stable system.

I guess if you're re-doing bends anyway, I would recommend acrylic. I switched from PETG to acrylic and found the bending to be not that much more difficult, and I find the piece of mind to be of value. Also, it keeps its clarity a bit better, so overall its a plus in my opinion.

The closest thing would probably be bong-cooling a PC which is more or less cooling the PC by sweating.

PETG can deform at relatively low temperatures, you loop fluid temperature was probably on the high side. This is a known phenomenon and EKWB even has inserts to prevent this from happening. https://www.ekwb.com/shop/ek-hd-petg-insert-10-12mm-10pcs I assume the tube looked something like this:

There you go, that's the spirit! Now just apply it to IT equipment too, you shouldn't care about what others think about your hardware, and you shouldn't care about what they can afford. Focus on yourself, and not of the IT equipment. Was that not the point of this thread? ha

I'm going to be 100% honest, I don't think the mental illness is the real issue here.

Easy to test, just don't use the daisy chain. Reminds me of that other crazy thread you posted back then.... But no, its not likely to change anything.

The only thing I would add is that Noctua and Watercool recently collaborated to produce a higher-static pressure version of the NF-A20 which sounds like its a overall better suited fan for this purpose. https://shop.watercool.de/Noctua-NF-A20-HS-PWM-chromaxblack_1

The power switch merely completes a circuit to short the two pins on the motherboard. So I do not think it is likely to cause any damage. Check the wiring of the switch to see if there is any damage that may be preventing the circuit to be completed, and that whatever mechanism in the switch is also making contact.

Stop obsessing about the income of others and what they can afford. Have you not listened to a word that people have been trying to tell you in this thread? (don't worry, its rhetorical). Its such a "you" thing that when you search "monthly income" on the search bar, you come up so often. Here are some snippets below.... But its nice to get periodic updates on your salary, and it sounds like you are getting some pay raises, here and there. Sounds like 2021 was a good time for you where you upped your salary more than 3 times, good on you! What's less helpful for you to keep digging and shaming yourself relative to others. You said you have a PhD, so I know the path you had to take to get that degree, and I also know that it can often feel unfair to spend so long and so much on education to make a low salary.

Still not biological, where it clogs and how long it has been there will change the appearance of precipitate. Just outside of the drain valve will be where the coolant is stagnant the most, so in many ways it makes sense for stuff to accumulate there.

Precipitated coolant related material, not biological.

Drugs to treat BPD, perhaps. I do not recommend cigarettes.
