Will disabling turbo boost and hyperthreading of a core i7 basically turn it into a core i5 with higher stock clock speeds?

So im choosing between an I7 7700HQ and an I5 7300HQ. They both run very hot in laptops, the i5 though a bit cooler (like 5-9 degrees C cooler) because of the lower clock speeds and no hyperthreading I guesse. So im thinking of getting the I7 but to keep the temps down when im extensively using the laptop under load i will set the maximum speed to 85%, undervolt, turn off turbo boost, and hyperthreading off to get below 75 degrees C. For short bursts i ll keep the stock configuration. By doing this though, do i actually gimp my I7 equal to an I5 by turning off what effectively makes the I7 an I7 or the I7 still has something more than the I5? Cus if not, i might just get the I5 lol

You really don't need to keep a laptop CPU that cool since they are made to run hot. Low 80's is perfectly fine. You might have better luck just replacing the thermal paste and thermal pads with something higher quality.

Technically yes, if you disable turbo boost for i5 7300HQ. An i5 7300HQ has 4 threads, a stock speed of 2.5GHz and turbo speed up to 3.5GHz. So, if you disable turbo boost and hyper threading of i7 7700HQ which has a stock speed of 2.80GHz, it will closely perform (a bit higher) to i5 7300HQ without turbo boost.
I'd suggest you to pick up i7 7700HQ. To make it cooler, change the thermal paste and undervolt. It will make a huge difference. My i5 7300HQ used to get heated about 90-95 degree C without undervolting and using stock paste during stress tests. After changing the thermal paste and undervolting about ~120mV, the temperature never exceeds 75 degree C.
