Upgrade or overclock

[Havocide]

Hey all.

I have been running at stock on my build from end of 2015 and whilst it has been running perfectly fine without issue I am debating an upgrade. Or at most overclocking. Though in my head if it isn't broke dont fix it comes to mind. Board and CPU below.

- CPU: Intel Core i5-4690K 3.50GHz (Devil's Canyon) Socket LGA1150 Processor - Retail
- Motherboard: Gigabyte Z97X-SLI Intel Z97 (Socket 1150) DDR3 ATX Motherboard

I purchased a 1080 when they where released and its been awesome to game with but would like to push it somewhat more as I have been running at 3.5 stock speed on the cpu forever. Being a novice at overclocking it always worried me.

However we attempted a mild overclock which indicated a issue with the water cooler not being very effective so couldn't even go higher than 3.9ghz my query is this.

Should I improve the cooling of the current system, so it can be overclocked to a higher speed. Or is there something out there now that would out do this CPU full stop.

Budget isn't really an issue but of course the less spent the better.

I have had this cooler since I had this build

Might be time to put some new paste on it or something. I am currently idle with an MMO in the background whilst I am working sitting around the 30-40oC but when I stressed overclocking it went up to 80/90oC and that was only the tiny upgrade. Nothing unusual going on besides having a browser open with several tabs, emails. Dont get me wrong it never 'struggles' at all but would like to push it somewhat for my bigger games.

Idle without anything is still around 30
