Extreme heat combined with water cooling
Extreme heat combined with water cooling
Hello everyone!
Let me describe my cooling set-up first
1. CPU Water Cooler Deep Cool Captain 120. On top of the case. Radiator -> Fan -> Case . Fan blowing out.
2. Fan in front blowing in.
3. Fan on the back blowing out.
3. Fan on the side blowing in.
4. CPU i7-4790K
Non-overclocked 100% cpu use - 75-80C . Overlocked even a bit, goes above 90C, so had to revert to stock.
Questions
1. Is the water cooling on case correct? Or should be be Fan -> Radiator -> Case . Or blow in may be?
2. There's another spare space on top next to the CPU one. Worth adding another fan or no point?
3. Anything else I can do to reduce temperatures? Or is the cooler really that crap?
Thanks IN advance!,

Thanks for the response. The pump is connected to CPU_2 and it pulses with color, indicating it's functioning properly. I plan to detach and replace it later. Would you suggest a suitable cooler for a 4790K? I'm open to both air and water options, but preferably one that supports overclocking. Personally, I wouldn't connect a pump directly to the CPU header; instead, use a power cable adapter to get power from the PSU. The Deep Cool Captain 120 won't be enough for an overclocked 4790K—no doubt the Noctua NH-D14 will do better. Read This Please. Please scroll all the way down to the final link in the post; it leads to an overclocking study and mentions a CPU tested in that research.
The 120mm radiator likely won't perform well with an overclocked 4790k, but it seems the pump isn't circulating coolant properly. Are you sure the pump is connected to a header for power? Does it vibrate as it should? Can you remove the radiator, tap it, and spin it?
An airlock might be the issue—when an air bubble blocks coolant flow.
I generally prefer not to use sealed-loop coolers due to their poor pump and radiator designs.
Thanks for the update. The pump connected to CPU_2 is pulsating with color, indicating it's functioning. I plan to detach and replace it later. Would you suggest a suitable cooler for a 4790k? I'm open to air or water options, but preferably one that supports overclocking.
Here’s a revised version of your text:
You mentioned the answer was helpful. The pump is connected to CPU_2 and it pulses with color, indicating it's functioning properly. I plan to detach and replace it later. Would you suggest a suitable cooler for a 4790K? It doesn’t matter whether it’s air or water, but one that supports good overclocking performance would be ideal. Personally, I’d avoid plugging a pump directly into the CPU header; instead, use a power cable adapter to connect it to the PSU. The Deep Cool Captain 120 won’t be enough for an overclocked 4790K—using a Noctua NH-D14 would give better results.

Make sure you scroll all the way down to the final link in the post; it leads to an overclocking study. One of the CPUs tested there is a 4790K. Check the cooling solutions described in the study for a comparison of how much overclocking you can achieve and which cooling method will help you reach your goals.
You’ll learn what cooling is needed at each overclock stage, so if some solutions are beyond your current needs, you’ll be limited to the overclock level your chosen cooler supports.
Good luck!
