Delid or nah?

[ApexKek]

Alright hey everyone,

I just recently put together my first Custom Loop and noticed the temperature on my 8700k has not dropped a single degree than from using my 280mm AIO from Corsair (80-83°C Stresstest).
Although the temps on my GPU have dropped significantly. I have 2 rads in the loop, one 420x30mm rad from corsair, and one 280x60mm from alphacool.
The CPU block is the EKWB Nickel plated Copper Classic RGB.
I used the thermal compound provided by EKWB.

Is the only way to drop my temps delidding with liquid metal and undervolting? If so is it really worth buying a delidding tool for 30 bucks, only to use it once and never again?

Thanks alot in advance.

Dekiding is worth it if you want to push the OC, I wouldn't recommend bothering with it just for the sake of dropping the temps.

Only you can answer that question. There is a risk in delidding and depending on the application and a bunch of other things you could see a temperature drop. But the temps you have are stable and unless you want to push it further 80C stressed is fine for longevity. You can do either or just know what benefits for both sides and the cons of both sides and decide which route you would prefer.

You can get a cheap one from ebay or aliexpress. I paid around $5 for aliexpress one it works. Delidded 2 8700k with it.

It sounds like you have the water going to the GPU first then the CPU. If you would like to keep that system, then yes the delidding(?) would help drop the temps a degree or two.

I used my cheap eBay tool for my a few cpus now. My last one being a my 8700k. 
made a large jump. Even went to thinner rads and got rid of one. Manage to keep both the card and cpu in the mid to low 40’s gaming. Normally have around 90% gpu usage but current game sits a bit lower.

You should try Monster Hunter World, this game is a real PC Rapist, CPU 50-80% and GPU at 100%.
It's most likely due to bad optimization tho on the CPU Utilization side... and 2560x1440p

Not sure that’s my type of game but I have enough usage issues as it is.

Order doesn't matter. As long as you have a decent flow rate the in and out temp at any point should be at most 1-2c

Delid makes 8700k at least by 15c cooler, however it does not make any sense if you are not overclocking. A Cpu is not a gpu it will not boost higher if it is cooler unless you overclock it. You never said in you post if you overclocking you cpu or not and vcore voltage you apply. Temps are fine (within the intel specs)

you will not see much difference between your old aio and a custom loop unless you push/oc it hard enough and try to keep the noise down.

at the end of the day cpu produces just as much heat with or without delid, LM helps to transfer that heat to the cooler faster.

Thought having it in my signature was enough, i got the CPU running at 5ghz at 1.35v, ever since i got it pretty much.

Mine is dellided and runs at 4.9 at 1.25 on with temps around 65-70c, it can do cinebench r20 at 5,2 with 1,38volts and hit around 78c. I think it would of hit the temp limit if it was not delided

I delidded my old 8600K CPU because I was not satisfied with my OC. 

Before the delid I was stable at 4,9ghz running 1,395V with max temps during stresstests was 85C.

After the delid I could increase my OC to 5,0ghz but also lower my voltage to 1,36V.

Despite running a higher overclock my temps dropped to 65-70C max during 8h Prime95.

I can definitely recommend delidding as it is very easy if you buy the correct tool kit. 

I was running the same CPU cooler as I am today: Corsair 360mm AIO. 

 

Imo the best thing about delid is that your PC will be more quite as your fans won't ramp up as much.
