Hi

I've overclocked my I5 6600K to 4.5Ghz and a Vcore of 1.275V and its being watercooled by a Cooler Master Seidon 120V VER.2
When i'm playing games (e.g. The Crew Wild Run, Forza Horizon 3) my CPU temps were crazy high (The Crew: 80C @ 1.275V, Forza: 95C @ 1.3V!!)

I recently applied new thermal paste so that shouldnt be an issue (be quiet! DC1) and my abient temperature is about 22C (does get hotter after long gaming sessions)

Is there any way I could cool the CPU down some more?? I want to see if I can get 4.7Ghz going

Thanks
 
Solution
Since you have watercooling, there is less air moving around in the case. And heat travels upwards so it travels from your GPU towards your CPU. For this reason I had to install a fan right next to GPU exhausting air from the case on the sidedoor.
A 120mm radiator isn't that good at cooling anyway. I would recommend 240mm minimum.
What are your temps in the case? Is your GPU exhausting heat out of the case or is that heat passing out of the case through the CPU rad? Room temps only make a difference if your rads are in the intake position. Otherwise your case temps are more critical. If you remove the side panel do your temps improve? If so then you need to re-evaluate your case fan setup.

Removing the side panel improved temps. The AIO Rad is mounted on the Rear exhaust fan mount with the fan on the inside of the case. Probably gonna move the fan to the front of the case
 
Sounds like you've got too much heat building in the case. I would keep the fan on the rad and add a fan as an intake. If you have a top or side vent you might consider adding a fan there as an exhaust as well to help give hot air another way out of the system rather than pulling it through the rad.

What kind of case do you have?

My case is the Phanteks Eclipse P400 with a side window
