Im wondering is there any possible way we can put water cooling in mac pro?

Of course it's possible, just design and do the mod by yourself. However, may I know why you want to do that? the CPU cannot OC, and the stock air cooler works so well. Why make it complicated and increase the chance of having trouble?

Because it is so entertaining to watch water and electricity mingle???

It's like watching "new love". Sparks and fireworks, and passionate flames.

there's videos of water cooled macpros on YouTube, looks like a pain but can be done.
you can also mount gpu's with water loops in to a macpro and stick the gpu fan next to the pcie slot fan.
seems pontless but have fun ^^

on tonymacx86.com you can find some rely cool hack's, my fave are in macpro cases, you can get a G5 cheep then stick a hack inside ^^ or even something older like a G4 case.

this one looks nice :D

i did love the G4 cube https://www.tonymacx86.com/threads/water-cooled-cube.98231/
and anther cube https://www.tonymacx86.com/threads/...ded-edition-my-2nd-hackintosh-case-mod.78479/ i do love them

I do Music recording and Video edit. I need my mac pro low noise as possible. That what. And My cpu heatsink temp seem a to high when I edit video.

I assume you are talking about the cMP (e.g. 5,1). The nMP should be extremely quiet and good enough for music production.

AFAIK, a good air cooler can be very quiet or even quieter than water cool. The pump in a liquid cool system is not that silent.

I do video editing on my 4,1 as well, the fan is not that noisy, CPU core temperature stay at around 73-76C, heatsink usually around 60C. If your heatsink temperature is high, which is a good sign that the CPU's heat can actually transfer to the heatsink. And as long as the heatsink is clean, the fan shouldn't need to work too hard to cool down the CPU (unless you have dual 130W CPU, that may require the fan to work harder than normal). My single W3690 system rarely need to spin up the fan to >1500RPM. And even though I won't call my cMP silent, but sure is a very quiet machine (even under stress).

The native fan profile may be a bit noiser, but you can always setup your own fan profile to reduce the noise and avoid overheat. I personally setup a profile that evenly spin up all fans, rather than heavily rely on the boosters. Let the intake / exhaust fan spin a bit faster and avoid the booster run at high RPM works very well on my 4,1. When my cMP under stress. The intake / exhaust spin up to about 1100RPM, and booster around 1300. Which is audiable, but not bad at all.

If you need a very silent environment, may be you have to locate the cMP a bit further away from the mic. Or use some noise absorbing material to "isolate" the cMP. I am not an expert in this area. But mod a cMP to be liquid cooled for audio production sure is not a good idea. That's way too much have to be done. And high risk of damging the Mac Pro. If you really need a silent machine to do the job, and macOS is a must, and you don't want to buy the nMP (assuming all other Mac is not powerful enough). Then the best way to achieve that is actually build a very silent Hackintosh. That's the easiest and most cost effective way to achieve what you need.

if you can say what the temps are or post a screenshot it may help

44-45°C isn't high.

Try Macs Fan Control for keeping fan speeds down. You want to keep CPU under 60-65°C and RAM under 85°C.

You'll probably find that the stock fan settings ramp up a bit more quickly than necessary. Exhaust fan usually has less effect on noise than intake areas, since it's further under the desk.

If your focus is solely on noise reduction, a full or partial enclosure would be the simplest and most effective solution. Partial is a u-shaped foam-lined box that you'd slide over the rear of the case with about 6" of clearance, allowing airflow upwards while containing noise. Full is much more complex, consisting of a cabinet with baffled intake fans directing cool air into the bottom-front of the cabinet and again baffled exhaust directing air out. Cables for a full enclosure usually come out thru a foam-gasketed door.

A partial rear baffle can knock 3-9db off fan noise and can be made with acoustic foam, cardboard or poster board, and spray adhesive. Wouldn't be pretty, but cheap, easy to make, and effective.

his fans are on almost the slowest setting, if the sound is relay to loud then some sound proofing may help temps look fine

The fans may have developed some bearing noise as well. I'd suggest a good cleaning to get rid of dust, and maybe consider replacing a fan if any one is noticeably noisy. I have an exhaust fan that isn't as quiet as it was 7 years ago. (Not loud enough to replace yet though.)
