undervolting laptop using intel extreme tuning utility

I'm using the Intel Extreme Tuning Utility (XTU) to set up my processor at a comfy 1.8GHz and now it runs like a champ! I'm ok manually changing the profiles if I really need the power consumption of the CPU.

I've recently figured out that a way to control the heat is to undervolt the CPU while still retaining a good performance for office stuff. I also use a DisplayLink dock at home, which has some CPU consumption and I assume that it could also have an impact on the overall heat and noise. I've already replaced the thermal paste and cleaned up internally for any dust and other debris (if any). Also I've made sure that the CPU is not botched up, as MacOS runs super cool (as it was intended).

However fans end up spinning up way too fast more often than not as the CPU usually heats up to ~65C at idle. Right now the CPU itself as it heats up way too fast, and I have to use MacsFanControl to cool it down appropriately. I would like to figure out a way of cooling it down with a respectable noise level and I'm trying multiple approaches. I currently use a 2013 Macbook Pro that still runs like a champ, and I'm running Windows 10 on it mainly (I prefer Windows, but I'm also using macOS with Boot Camp, I am aware of the weird setup).
