You should check out HWiNFO if you haven't already. It's my favorite of all the applications out there for monitoring the system. There's a forum on the site and the author of the program is very helpful.

You can download Haven or Valley from https://unigine.com. Run one or the other in loop mode, but not at full screen. You can put your monitoring software window on top of the Haven/Valley while its running. If you do this you can see in real time what your temps are doing. Haven/Valley will very closely match gaming performance.

I know it's fine, it's well within the ratings of every component, lower temperatures just make me feel a bit more comfortable.

I do use HWiNFO actually, it's fantastic! I was referred to it in the Skylake Overclocking guide and used it to watch my temps and other things while learning how to overclock.

I'll have to give those a shot, I've just been using Furmark to test stability for my GPU.

This is one of the reason why my new build will have separate loops for cpu and gpu. I don't like one component influencing the temps or characteristics of the fan curve of another. I also don't care too much about the pwm controlled pumps as it ramps up too, which I'd rather it stay at one speed. These are some of the things I've discovered with my 1st water system and why I am getting one the Aquaero controllers, so that I have complete control of all that stuff.

I am with the camp that goes with a single loop. If loop temp is high because of insufficient heat exchange (radiators) it will be high with one loop or two. It does not matter. By having a single loop all the radiators capacity is available to all components. In most common uses all the components are not at full load at the same time. I have multiple temps sensors in my loop, some after blocks some after rads. Never seen them more than 1C apart 99% of the time they range .2-.3c Controlling fans on rads with air/water delta as opposed to component temp is much better because the coolant temp increases slowly compared to component temp. If controlling fans by component temp you are always trying to catch up to the load because the coolant has increased in temp. The coolant will take longer to cool down as well.

I thought about doing that, problem is I have a full cover water block that covers my fan header. I might be able to squeeze the wires out though, not sure. I think I'm going to stick with adding an extra temp sensor. Thanks for the input though! smile.gif

I am using PWM header from my GPU to control my fans just as suggested. I had to modify my blocks though, dremeled out a little slot in the Acrylic cover so that the pwm header and wires would fit with the block mounted. Using MSI AB it is a great solution.




Definitely try Speedfan first if you can, that would be a very nice free solution as well.

I would agree there are pros and cons to either style. Draining and filling would be nice with dual loops in my opinion, or just loop maintenance in general. If you have a small problem somewhere, or want to make a change, it's only half of the loop that has to go down to fix it. I do like having all the rads to cool the GPU when the CPU isn't doing anything and vice-versa though.

I actually really like PWM pumps though. Having used a fixed speed DDC, a vario D5, and a PWM DC-12, The DC-12 was actually my favorite. My D5 does this funny thing where as soon as I crank it past 1, and until 4, it has some sort of resonance with something in my case. Maybe it's just a decoupling issue though. The DC-12 was awesome how it would just run 800 RPM until my system got hot and then it would crank up to like 1200.

Either way, the new temp sensor seems to be doing it's job, The fans on one rad are ramping up with loop temp, and it's taking quite a bit longer to reach an equilibrium temp, which definitely means said temp is lower due to increased cooling. I think I'm gonna set it up so the fans on my other rad do the same thing. Thanks for all the help everyone!

That's a sweet mod actually. That cable looks really nice too, and it looks like you might have the same flush cutters as me lol. I got the temp sensor working for me, I like the idea of going off of the coolant temp as opposed to hardware temp as RDKing2 mentioned.


Edit: I guess I should post temps too lol. After a couple hours of running Valley on pretty high settings:

CPU: ~61C
GPU: 57C
VRM1: 62C
VRM2: 49C (I think those VRM names might be backward in HWInfo, I remember VRM2 being the one that is supposed to get hot)
CPU Controlled Fans: ~635 RPM, went as high as 920 (hence wanted to get these loop temp controlled as well)
Loop Controlled Fans: ~1200RPM

Logged via HWInfo

Loop Temp: 40.3C

Logged via XSPC Temp Display with Phobya Temperature Sensor Plug located in reservoir.

I am with @RDKing2 on the multi loop issue. The cooling potential of that radiator space is wasted when not being utilized in multi loop configurations. I recently faced this question myself and after some research decided to go with a single loop with dual pumps rather than break it up in to single pump loops.
