Hi folks.

I've been out of the WC game for ages...my last WC machine was a q6600 in a thermaltake mozart case..I think I had 2*120.3 rads for that and a 8800gtx.

I have now got a small server rack in my garage which houses my router (forcepoint 1100) and small pc (4650g based ryzen server ).

I am wondering if it is a good idea to invest in a large radiator to put on the side of the rack, a big pump, reservoir, and a bunch of quick disconnects( I presume this technology has come on a bit since my days).

This will be to cool the ryzen and the router.

Has anyone done anything like this before or is it just a big fat waste of time and money..?


(Aim is for less noise )
 
So im about to do this now -
I am going to put my radiator on the floor of the rack to pull up cold air through the rad and into the rack.
The PC will be quite high up - do I need to put the pump the highest, or can the PC be the highest bit of the system?
I did order some QDs but I think the ebay seller isnt going to be sending them.
 
I think it's a d5 pump I have (although somehow I have ended up with 2 of these and a DDC).
I'm more worried about air bubbles.
If I have the rad flat at the bottom of the rack, fans pushing air into the rack. Then the pump and then highest will be the pc itself.
Will this cause issues in filling the loop and draining air

Going for quieter air cooling would be my first port of call.

Even if you have the worst case scenario with 1U devices with 40mm fans that have to spin fast to cool the server, if you have the space and don't mind it looking janky, you may consider removing the 40mm fans attaching larger fans via a duct. Getting a custom duct 3d printed would be cheaper than getting even a set of quick disconnects.

Yeah I thought about this.
I have wanted to get back into water for ages. I actually have all the bits now, some are coming this Friday..just gotta get the mayhem's stuff now then I'm all ready to rock and roll.

I will eventually water cool my forcepoint router..that's the ultimate goal.

I just moved to a 5900x and it's currently running no less then 65c idle. Hopefully this will be better

Given the height you're potentially working with, having the pump at or near the top of the loop is pretty important. D5's are great, but they don't have *that* much head pressure to push liquid up 1m+! Plus filling would be a nightmare if you ever have to turn off the pump and it all comes flooding back out again :cry:.

Thanks - im still in the process of planning it all as I have the bits. this little computer runs my plex + homeassistant so downtime is not preferred, but looks like ill need to re-configure the rack...


really silly question - is there any reason I cant use the plug on the top of the res to hold the res /pump up? ie. drill a hole into top of rack, and pop the res plug through it, into top of res - this bit doesnt need to be water-tight does it?

i ordered a lot of stuff, but a fillport wasnt on the list... i do seem to have ended up with multiple res's though.
