Hello, I am planning to upgrade my pc and idk if i should get the 6700k or the 7700k? I am currently using i5 3350P. I didn't bother reading about the 7700k until now and I see a lot of people had problems with temp spikes. Or should I just way for the 8th gen? Also, what cooler would you recommend? Would it be bad if I used the cooler on my i5 3350p until I buy the mobo, RAM,CPU? Did the temps fix with the BIOS update or to have good temps I have to de-lid the CPU?
Also what thermal paste should I use?
Thanks

I7-7700K is about as good as it gets for gaming today.
It runs at 4.2 stock with a higher turbo.
That is not far from overclocked speeds so expect reasonably high temperatures.
Your 3350P has a tdp of 69w.
The 7700K is 91w.
So, yes, your cooling requirements will be up a bit.
But, I would not worry, you can use your old cooler, at least temporarily.
Hopefully, your case has good intake airflow to supply the cooler.

I would not delid the processor. You will void your warranty.
The key to heat is to control the vcore. As you oc, the vcore will increase, and added heat will be generated.

If your case permits, buy one of the new noctua s variant coolers.
NH-U12s, NH-U14s, NH-D15s.
They are engineered with an offset to clear graphics...

NH-U12s, NH-U14s, NH-D15s.
They are engineered with an offset to clear graphics cards and ram sticks.
The included noctua paste is fine.
I oc my 7600K which is also a 91w tdp unit to 4.9 using a noctua NH-U12s with no issue.
And the fan is not running full out so it is quiet.

FWIW
As of 2/22/17
What percent can get an overclock at a somewhat sane 1.4v Vcore.

I7-7700K
4.9 78%
5.0 59%
5.1 28%
5.2 7%

Tell me more about your prebuilt.
If you are using the stock cooler that came with the 3350P, it is of minimal height and cooling capability.
OK to start with, but really not what you will want long term.
The key to the cooler you can use will be the height available to install it.
The good ones will be tower type coolers with a 120mm fan or better.
Typically, you will need 160mm height to install a cooler like the scythe kotetsu.
If you have 145mm available, the cryorig H7 is a good one.

Then, do you have a motherboard that permits overclocking.
If not, the 7700K will run at stock and a modest cooler is fine.

By adequate intake air, I think something like two 120mm front intakes.
That is usually sufficient for a 7700K and a modestly strong graphics card.
If you have less than that, you are looking at stronger(and noisier) fans running at higher rpm.

If you do not know the name, a picture can help.
If you do not know the motherboard, CPU-Z will identify it.

My current mobo is GA-H61M-S1 (rev. 2.2). GPU GV-N65TOC-2GI (rev. 1.0). Using stock Intel cooler. I will be getting a Z270 mobo. Can't take any pictures rn cuz its 00:39 here. Also I have an Inter-Tech Energon EPS-650w which I'll be changing to a (probably) EVGA Supernova g3 750w. For GPU not sure which model because if I'm going to change so many parts its kinda a new build so probably gonna buy a new case aswell but I will be going with a GTX 1070.
