I've heard that turning off hyperthreading can cool down the CPU temperatures.I don't know how much but I also heard that it can really effect playing games. My question is, Is it worth turning it off just to lower the temperatures a little or not?
Thanks.

Well, your choice is either:

1) Turn off hyperthreading, and your CPU will still run at the same load, just for a longer time, maybe a little bit cooler.
2) Turn on hyperthreading, and your CPU will get done faster and be able to cool off sooner.

The circuitry to enable hyperthreading is minimal, remember, you're not actually doubling the number of cores, you're enabling the circuitry which allows the cores to store idled thread states and pick up thread states and registers where it left off while that thread was waiting for resources/data/results to become available.

An i5-4690k is a quad core part. An i7-4790k is that same quad core part, with the hyperthreading circuitry which presents more logical (not physical) cores to the OS. Actual electrical load is minimal which is why it's still pretty much rated as the same wattage as the equivalent i5 part.

First thing: My temps are quite good, actually very good. On idle, it's around 30c ish (is that even a word ) On Normal around 50c and on load 80, 85c.
I selected you as the best solution ( and not seduction ) sorry.

Say I was going to overclock it wouldn't make a huge difference correct?
I mean after researching which wasn't enough, obviously, some people said that Hyperthreading was a huge thing when Intel added it. Am I right or not?

You have the wherewithal to do some experimenting to find the best answer for YOUR games.
Few games can actually make use of more than 2-3 cores, so hyperthreads will benefit you little.
If disabling them allows you to oc a touch higher, that could be a winner.
If you have a i7-4790k, your highest OC will be limited by your tolerance for a unsafe Vcore before you run into thermal limits

I think hyperthreading is a much bigger plus for I3 than for i7.
A good way to think of hyperthreading is like added cores of 1/4 full capability.

Everything that I have read suggests an additional 100-200mhz difference at best when overclocking with HT turned off. Honestly 100-200mhz is not going to give you any kind of noticeable difference. You are much more likely to gain a larger benefit from the HT were HT is utilized.

A lot depends on which i7 you have. An i7-4790k? It's a premium binned part, base speed 4ghz, turbo up to 4.4ghz. Maximum speed maybe 4.7-4.8 ghz if you have a -great- sample. Would you notice an extra 7% in speed? Maybe. Probably not though.
