Temp very,very high after adding another radiator?

[Shadowman]

Ok something is not right here basically last year

i9 7900x delidded and thermal replaced with liquid metal
360 radiator with 3x Noctua AF12 Fans

Room temp: 29c
Water temp: 40c
i9 7900x at Full Load With Aida64: Max hit 78c after 1 hour


This year about 3 months ago (build was actually fully completed 2 days ago, system first time turned ON 2 days ago)

Replaced the i9 7900x original IHS with the RockitCool copper IHS (3 months ago)
Added my GPU also RTX 2080 Ti
Plus added a 480 radiator (4x Noctua AF12 fans) to go with my 360 radiator

Room temp: 24c
Water temp: 31c
i9 7900x at Full Load with Aida64: Max hit 88c  within 15 minutes
GPU tested also Full Load after 30 minutes max temp was 42c

You see from above something is seriously wrong, yes I added my gpu but also added another radiator (480) I mean the water temp is way, way cooler now because of the added radiator so I was actually expecting the temps to come down maybe a little. Something is telling me it's the RockitCool copper IHS that I put on the cpu die obviously using liquid metal.

You are either running out of pump power or you got air in your system. You got one massive radiator setup.

Is the CPU block properly seated? Check the thermal paste imprint, to see how it's spreading.

Thanks,I did do a test before filling the loop with the EK leak pressure tester  but wouldn't the gpu be effected also then if it was air? I mean the temps seem ok for the GPU 42c max on full load. In regards to the pump I have a Aquacomputer flow sensor connected to the Aquacomputer Aquaero 6 flow rate is at 1.1 GPM (Gallons Per Minute)

Shouldn't be pump power if you have a D5 variant.  You don't say what the pump is but most are capable of pushing 2 rads like that.

GPU being only 42 tells me that the issue is with the Liquid Metal, IHS or mounting.

*Just to add overclock was the same for both times 4.7Ghz at 1.18 Volts

*Pump is Koolance 450s with speed controller

Liquid metal corroding into the copper IHS. You probably need to delid again and re-apply liquid metal. The nickel plated original IHS is far superior to these pure copper nonsense.

Thanks, been reading also about this and the fact is I actually put liquid metal on the underneath of the copper IHS as well (which is ok) but the thing is I did this like over 3 months ago and the cpu with the copper IHS on it just set there in the cpu socket with the water block mounted on it (this was a very slow build)  I started the system up first time 2 days ago could this have made it worse?

Liquid metal readily seeps into copper over time, and so it is expected that while the initial temperatures are a bit better than the nickel plated IHS, they rapidly degrade over time and it just get drier and drier inside the CPU. If I were you, I'd undo everything, bin the copper IHS, dig the stock IHS back out and call it a day

Thanks for your help really appreciate it, yes I shall do that (this is the time that I wished I'd used soft tubing instead of hard tubing  )
