Upgraded i5-7400 to i7-7700k and now overheats

[Rigglets]

So I had an HP 580-023w desktop, I completely overhauled it. Now its in a Corsair 220t Case, got a MSI GTX 1080 Duke GPU, and a Corsair 850w modular PSU and 16gb of DDR4 2400 Ram. I am using the stock CPU cooler that came with the i5-7400 (was bigger and had a bigger heatsink than the one that came with my i7-7700k). I did see the Odense2-k does support i7-7700k up to 91w. When playing games I get to really high temperatures. 80-90C. What can I do to fix this issue? Use the smaller CPU cooler that came with the i7? Or Install a Corsair H150 360mm AIO Cooler that should be delivered tomorrow. BIOS is up to date. Drivers up to date. Just trying to game without it overheating. Not trying to overclock right now, just want it stable and cool enough to play games.

Specs:

Windows 10 64bit

I7-7700k 4.2ghz

16gb Ram DDR4 2400

2 sata ssd's (250gb/500gb)

1tb HDD

MSI GTX 1080 8gb DUKE GPU

Odense2-k Mobo

850w PSU

@Rigglets , welcome to the Community.

Here are the Product Specifications for the computer.  If you look at the section titled "Processor/Processor upgrade information" you will see that the i7-7700K is not listed as compatible.  This is your problem.  The motherboard is simply not designed to run the 77800K. The TDP for the 7700 is 65W and for the 7700K it is 91W as you stated.  Here is an article that will explain the differences.

But if you look at the specs for the motherboard, Odense2-k, it states under processor upgrade "Up to 91w TDP" So im confused

It's not a problem with MoBo supporting (or not) this CPU - if spec says it does, then it will (as it invariably works fine, correct?).

The problem lies with the weak CPU cooler, i.e. heatsink, assembly and fan that most likely needs to be different (stronger) for i7.

Also please note that HP uses proprietary fittings and stock coolers might not work with your MoBo & PC enclosure.

I've been in the same boat - see my posts from the past - and ultimately decided not to upgrade this CPU. To be honest 4 years down the line I'm still fine and this PC is more than adequate to what I need it for,
