Is It time to delid 7700k or for RMA

[sloke123]

Hi,
Recently I have noticed that cpu gets hot while playing games( temps around 80~82°c). I cleaned the fans fans motherboard, cooler and changed the thermal paste but the results were same. My PC specs are
1. Intel Core i7 7700k( @ stock Frequency)
2. Corsair H80i
3. Asus Maximus IX Hero
4. Gskill Ripjaws V 16 GB(2x8 GB)
5. Gigabye GTX 980 Ti G1 Gaming
6. Corsair RM750x
7. Corsair Carbide 400R
8. 5 120mm case fans ( two at front, two at top, one at bottom)
I did some test which I like to share-
First test was @32°c room temperature, case fans are @ 1200 rpm, Cooler Fans @ 2600 rpm. CPU temp went to 90°c within a minute.

Second test was @25°c room temperature with AC on, case fans are @ 1200 rpm, cooler fans @ 2600 rpm.CPU temp reached 86°c after 3 minutes.

I did a Prime95(v26.6) test but cpu temp went 90°c immediately, so I had to stop the test.
My question is,
1. Should I delid my CPU to get better result?
2. Or something wrong with my CPU( It has 2 years warranty left)
P.S: My idle temp on first case 32~34°c and second case 29~31°c

Halloo guys,
I'm very much sorry for my belated reply . It is year ending time, there is a lot of work pressure in my office.
Anyway, I bought Cool Laboratory Liquid Ultra, 3D printed delid tool, and Thermaltake Core P5 open air PC Case.

I made a cooler bracket also, coz my cooler's tube length is too short.

I delided the cpu and apply the CLU in between the CPU Die and IHS. Didn't use ant glue to relid it. Just use the CPU retention bracket that comes with the motherboard..

After a few minutes, I did a stress test and the result was astonishing. I didn't expect that.
Here is screenshot of 20 minutes stress test

Cpu Temp never went over 75°c.
Thank you all for your valuable suggestions.

No worries, Sloke. Glad we could help!
