4790K successfully boosted to 5ghz using water cooling.
I finally achieved 5ghz on water cooling after some adjustments and patience. With a few tweaks, everything seemed to work well. 4790k at 5.0ghz 1.41v MSI G45 gaming with a custom loop from EKWB. I was lucky enough to push my chip all the way to 5ghz using the multiplier, which is quite rare. Here are some pictures of the CPU after delidding and leveling the waterblock for a flat surface. Before, it was getting very hot at around 4.9ghz. Now the cooling time looks much better. The last photo shows the waterblock finally leveled. I could have thought it would be better centered for contact, but it ended up being off-center on the side. After stress testing with XTU, the results were impressive—though the crop was a bit odd.
KeelinTy shared their experience achieving 5ghz on water cooling with modifications and tuning. They mention using a custom loop from EKWB, a multiplier of 50x, and overclocking the chip to reach 5ghz. They also describe the process of delidding the CPU and adjusting the waterblock for better contact. The final benchmark results were recorded in XTU after stress testing, though they noted some unusual visuals.

I managed to get lucky with my chip by overclocking it all the way to 5ghz using the multiplier. A 50x boost is quite rare, haha.
Here are some photos of me delidding my CPU and then fine-tuning my waterblock for a flat surface. Before, it was getting up to 90c at 4.9ghz.
Now the lap time is much better.
As you can see in the last photo, my waterblock wasn’t flat before. I guess it was too far off to the side, which affected contact.
Here are the benchmark results after stress testing with XTU. Sorry for the strange crop image.
what tools did you use to lap the heatsink?
I used two sheets of sandpaper—one semi-fine and then a really fine one. I don’t remember which grit exactly ahah.
KeelinTy shared their experience on achieving 5ghz with water cooling. They described the process of modding, lapping, and time investment, resulting in a good outcome. They mentioned using MSI G45 gaming with a custom loop from EKWB and overclocking to 5ghz using a 50x multiplier. KeelinTy also detailed their CPU overclocking method and the challenges of achieving a flat waterblock for better cooling. They noted issues with uneven contact and the need for honing the heatsink surface.
