[SOLVED] Is my AIO working properly?

I just installed a Thermaltake Water 3.0 which has 3 120mm fans. It is at the top of a Corsair 780T with the fans mounted above it in a pull/exhaust configuration. The 3 fans are connected to a splitter and plugged in to the cpu fan header. The pump is connected to the aio pump header. I have set the aio pump to DC in bios and adjusted it to run at 100%. Bios reports the pump rpm at approximately 1750 rpm. According to what I have read the rpm only reports half the actual speed so you have to multiply by 2. The pump is rated at 3600 +- 150 rpm so I believe I am getting 3500 rpm which is within specs. I can't hear the pump running but I can feel the rubber hoses vibrating. The problem is I can't feel any significant amount of heat anywhere. One hose is just warm enough to notice. The other is not warm at all. The radiator is not warm to the touch. The air being exhausted is not particularly warm. The plastic cover over the pump with the Thermaltake logo on it is just slightly warm. Shouldn't I be feeling some moderate heat somewhere? I have to assume it is working because if not I would expect a stress test would have my temps so hot it would throttle. I am currently seeing temps around 183 during a stress test. My idle temps are at around 90 F.

Is is possible that since this is a 360mm radiator that there is so much surface area it distributes the heat evenly? I still think I should be feeling heat somewhere?

See I disagree, I think there is something wrong below your IHS if 3 of your 4 cores are running cooler. I think you need to go all the way back to the beginning and work it that way. And if Grizzly says use the spread method, use it.
What are you using to stress test it?

What are your ambient temperatures?

Please use Centigrade, Fahrenheit is not commonly used in Computer circles, makes it much easier to understand.

Based on the temps you did give it certainly sounds like your system is running and cooling properly. If the air just doesn't feel that hot, well... maybe you have tough skin. "feeling" is by far the least scientific measure you can use. If the system is reporting 83C and you're stress testing, its 83C.
 
I have used OCCT and AIDA 64 for the stress tests. The ambient temperature is 20 C. At around 83 C I should be feeling some heat somewhere in the AIO loop wouldn't you think? Thanks.

Room is pretty cool, you should feel heat from the radiator somewhat, but the fact you are not isn't exactly concerning. If there was a problem the system would be overheating. I am assuming you have also tried to feel the temps inside the case for comparison?
 
The airflow in the Corsair 780T is very good. I have all the hard drive cages removed. The temp of the air coming out of the rear exhaust fan is about the same as the exhaust fans for the AIO radiator, cool. If I remove the side panel everything inside is cool except a minor amount of heat coming off the 1080 Ti.

I am wondering if the heat transfer isn't optimal between the IHS and the water block. I have ordered another tube of Kryonaut and am going to remove the water block and look at the pattern of paste to make sure I had good contact.

What CPU are you running, and is it overclocked?

I mean in theory that cooler should be giving you lower temps than 83, but 83 under stress testing isn't bad. You may have a paste issue. Did you use pre applied paste or your own?
 
I don't know how to link another question I asked earlier to this thread so I will reiterate that information here.

I removed the pre applied paste that was on the water block and applied Kryonaut. The cpu is technically not overclocked, just set to run at 4.5Ghz all the time.

I have an I7700K that I just delidded with the Rockit 88 kit. I used Conductonaut applied to the die and the IHS. I used the spread method with the Kryonaut on top of the IHS. I then had to remove the water block to reseat the cpu so I used the pea method the second time. This is where I think the paste might be the issue with heat transfer. I am not sure how well Kryonaut spreads itself with the pea method. Thermal Grizzly instructions say to spread it.

After adding the AIO cooler along with delid I was expecting to get a big temp drop. Temps actually increased. The 83C I am getting with OCCT test is only because I lowered the core voltage from 1.20 down to 1.110. At 1.20 volts I was not able to complete the test as temp would rocket to 85C and shut down the test. I tried the CPUZ stress test and it ran at 93C. Before the delid I was able to run OCCT at 82C and 1.20 volts.

I am also getting core temp readings where core 2 is reported at 80C while the other 3 cores are running at around 50 to 60C. When I use AIDA 64 core 1 is being reported as the hot core with the other 3 all close together.

Between the abnormally high difference on the 1 core and overall higher temps than before the delid, something is definitely wrong. I am 99% sure I applied the Conductonaut properly so the only thing I can think of is a bad "pea" application of the Kryonaut between the IHS and water block.
