So i have an i5-4690k on an asus 97 board and it idles at around 25c.

When I installed the coolermaster evo cooler, I got everything on there tight, but if I twist the heat sink it'll wiggle a bit, but makes contact and I coppied what a guy did on youtube.

Running prime 95 on blend, after about 5-10 minutes of the cpu running at 4.5ghz, the temps slowly climb up. I shut of prime 95 via task manager when I saw 1 core go up to 90c.

Is this normal. when it was at 90c I touched the heatsink and it was warm but more on the cool side.

It's normal that the heatsink doesn't get hot. If it did, it wouldn't cool, huh?
90c is too much, however. Too less/much thermal paste, maybe? Or too much voltage? Common problem with prime95 is voltage is on "auto" mode.

I have an asus motherboard that automatically overclocks. Maybe i'll change the jumper on the motherboard to not allow voltage increase

Don't EVER use automatic overclocks. If you're already voiding warranty, at least do it safe and stable instead of getting a program or oc feature to overvolt and melt your cpu on same or lower clock speeds that you'd achieve manually.

Definitely steer clear of automatic overclocking, the settings it uses are too generic. Have a read through some overclocking guides and learn how to adjust CPU voltage, as that will affect CPU temperature the most.

Also bear in mind that the 212 Evo is a good cooler but it's far from the best, and it's definitely not suitable for high overclocks.
