Dual Rad Questions

[Vajra]

Hello!

I am in the process of purchasing a custom loops using EKWB configurator and it has recommended two radiators for my case.  I know this is likely super overkill but I want to give it a shot anyway as it's more about the tinkering for me than being efficient here.  My question is around the configuration of the radiator in the loop.  What order should the radiators go in?  For instance, should I go pump-rad-cpu-rad-gpu-pump or pump-rad-rad-cpu-gpu-pump?  Or some other configuration?  Off the top of my head it makes sense to go rad-cpu-rad-gpu.  Thanks.

from all the testing i have seen there is no differance in the max temp you will get to no matter what order you go in, so just go whatever way is the easiest in your case

There isn't a difference with loop order as long as the res is above and right before the pump so it doesn't run dry.

Coolant temperature will mostly stabilise at a given temp (varies). Yes if you go CPU block rad GPU block rad, if the coolant was completely cooled to ambient by time it leaves it would cool batter, it usually isn't, but it's be cooler BY A WhOPPING 1°c to do it that way (maybe not even 1)! That is so insignificant you won't notice, and running a loop like that might add more tubing which would reduce flow more, while that actually don't matter again, it really doesn't matter, once your pump never runs dry the loop will work well, lay it out however best you think it looks. I'd say to add the rad too, I have a single 240 for my i7 7700K and VRM, and it can get sorta hot when really pushing the OC on 1.5v 5.3GHz.

the amount of heat even a very high end overclocked system can kick out is not enough to make loop order matter.

I really appreciate the responses, thanks everyone!

Would you say that getting a block that covers the VRM is worth it if I plan to OC and run streams from the system?  EK has one for my board I just don't know enough about them to know if it's mostly aesthetic or not...

I don't super like monoblocks, I think they look like someone just blobbed a lot of plastist on a board, and I prefer separate VRM blocks, but my board came with a VRM block by default, so it was a no brainer. If you want to take some more heat off a board (the VRM is usually the 2nd hottest part of a board) for lower fan speeds (the board can sink more heat into the mid ground plains that come from the chipset and RAM for example) then yes, sure, go for it, you can reduce the need for cool air inside the PC a little, as the only thinks to cool now are the PSU, RAM and PCH. Would I recommend spending money on the block, no, not unless you're doing like a Jayztwocents Skunkworks/Red Mist kind of build. Now you're doing hardline it seems, so that would look nice maybe having the tubs sleeking around your PC, but I did it because I had my CPU super overclocked with the VRM set to performance, it dumps a lot of heat due to that, extreme phase response and everything on 800KHz switching frequency. On air it still only hit 60°C but the block had the threads and I had the fittings so I did it.
