As depicted in the title, My temps for my new i7 are extremely high. Even with running water cooling my temperatures are 10-20c higher than they should be. My idle temps can be anywhere from 35-45 Celsius with spikes to 55. and while under like 30-40% load the temps burst higher up to 80s and after 15 minutes at 80s they rest around 85-95 Celsius with spikes to a max of 100 no higher. However when stress testing my CPU, the usage reaches 100% but it still doesn't go over 100 Celsius? Anyone who has any advice please help. Even if your suggestion is to slap my cpu with a wet towel.

Originally adding these components to my PC, i could only fit 1 fan on my 240mm liquid cooler due to high profile ram, after seeing these temps i managed to fit a second fan onto the cooler hoping it would fix the issue but surprisingly that wasn't the issue.

Things I've tried:
Adding thermal paste to what I had already put on there from my installation (I cleaned it of old paste prior to installation)
Increasing fan speeds via BIOS
Different hardware monitors, currently using CPUID HWMonitor

Hardware:
CPU: Intel i7-7700k

Motherboard: MSI Z270 SLI

Cooler: Enermax LIQUIMAX II 240mm

Thermal paste: MX-4

For those temps it seems like the pump on your water cooler is dead. Have you tried it with an air cooler? If not, feel the tubing on your water cooler and if there's no vibrations whatsoever then your pump is likely dead and needs replaced, since those temps are uncharacteristically high.

Is it possible that they died after a quick replacement of my processor? It worked just fine before with my i7-3770k.

Probably not, which leads me to think that your cooler might be seated incorrectly then. Reseat it and make sure it's properly applied to the CPU. The idle temps are fine which probably means a part of the cold plate is touching the CPU, but it isn't seated fully to cover the whole CPU.

You also may still want to check if your pump is working.

Got it, I'm retesting temps right now cause i've only gotten 2 small chances to do so in the past few days and the results varied between tests, i'll test that right after i get some readings and i'll post if i find anything about the tests as well as findings with my pumps and after i tighten and or readjust my seating of the cold plate. Gonna do that now.

I removed and re-adjusted my cold plate or whatever you wanna call the part that sits on the CPU, there was some torque in the tubes so i rotated it to remove the tension etc and replaced it on tightening the screws, except now my temps are resting higher and PC startup reached higher in terms of temps as high as 75c. resting temperatures now are at 45-50c hoping it'll cool down. The pumps are also working both tubes i can feel vibrations.

Anyone have any other ideas?

You cleaned off both the cpu and plate of old thermal compound and reapplied using the proper application method I assume?

I don't know of any real proper methood, i just put around 9 dots of paste around the top. there's definetly alot of extra compound on there so it's not a lack of compound. I cleaned it off after i removed my 3770k, other than that it hasn't been cleaned again (by again i mean anytime after i applied paste for 7700k)

Too much compound can be an issue, and your application method can leave air pockets which also cause higher temps.

The method over the years has always been a dot about the size of a pea in the center of the cpu, intel started recommending a very thin line along the kaby lake cpus.

I would try applying the thermal paste properly before going any futher and retest. There is a good chance this is your issue.

Alright I'll try re-applying right now. Just a moment.

I would also recommend removing your old compound with rubbing alcohol and a coffee filter or paper towel if you can do that.

Those are readings from it, chances are it is set to auto vcore because i haven't dared touch the voltage on it.

I've reapplied the "proper" intel way, cleaned off CPU and Cold Plate with rubbing alcohol prep pads, Resting temps have moved back down to around 38-43c i have yet to test gaming temps.

Need to see the other half of image, crop left side out.

What is vcore under load in windows?

VID is fine for those clock settings. How exactly do you have your cooler setup? What leads to what headers? What cooler is it? When you installed, please describe exactly how you stuck the 'cold plate' (that's actually the pump if it's an aio) to the cpu, what pattern, did you thumb or screwdriver etc.

Alright, here you guys go this is a video showing nearly all of my setup. I tried to explain as many questions and show you guys everything about the problem.

And big lizard im going to test voltage under load in windows right now, I'll get back with results in just a moment.

Have your single rear case fan pull cool air in. Use it as an intake so it won't steal air from your CPU cooler. Turn around the single case fan on the bottom into an intake pulling cool air into the case from on bottom. Make sure the single case fan in the front of the case is an intake pulling cool air into the case. Only fan blowing out are the two on the radiator. Make sure radiator is free of debris like dust build up. Clean fan blades with rubbing alcohol to help air flow.

https://gyazo.com/409c78404aefb4d7e4427f70c660da05 so you're saying to rotate this fan here at the bottom of the picture? Completely flip it to turn this fan to an intake?

Yes, make sure all 3 of your case fans are pulling air into your case, and that the air is being pushed out through your radiator. Turn your computer on for just a few seconds to make sure fans are pulling air into your case. All 3 case fans look like they are blowing in the wrong direction looking at the fan blades.

HAHAHA, I just love that you spent time making a diagram for it mate. Thank you lol i'm going to do this right now and i'll post photos of the updated setup.

You don't need that rear exhaust fan at all, either as intake or exhaust. There's ample airflow from the 2x rad fans for exhaust purposes. That leaves the bottom fan and front fans which should be intakes.
The pump is exactly right, it's on cpu_fan header. The 2x rad fans should be on a splitter (supplied with the rad) to a single header, doesn't matter which.
Now. Get rid of that fan controller. You absolutely do not need it. That msi board comes with decent mobo software for running the fans. Use it.
Open up the bios, search through until you find the settings for the fan speeds. Cpu needs to be 100%, not auto (it might be grayed out, that's fine, means it's full 12v and not controlled, which is what the pump needs to be at). Sys 1 and sys 2 are usually auto, 3+4 are usually 50%. This is fine. It'll be over-written by the mobo software later.
In my control center on my msi, the fan settings are under the Green tab for some really stupid reason I have no idea why. Make sure cpu is set for 100%, not on smart-fan etc. This is where you set your fan curve for whatever headers your fans are on, which should only be 3 of them, splitter for rad, splitter for fronts and single bottom. Good controlled airflow will keep the case/cpu cooler than just blasting air, so play with the curves till you are happy with the results. You'll probably not need high rpm from the bottom fan, more so from the front intakes.

Once you take pump, airflow, fans etc out of the loop, you'll have less to double check if temps are still unacceptable.

BTW, video was great, lol.

Would still like to know what vcore is? My best guess is that it's higher than what VID is showing.

Have seen many boards with vcore on auto(regardless of what VID reads) overvolting, sometimes as high as 1.5v. And in my experience MSI seems to be the worst at this.

Fixing airflow alone will not solve heat problem if voltages are too high, although I agree there are issues here.

Having learned my lesson well as far as airflow and cpu coolers, the first thing I do on a new build is to optimize voltages (especially with 7700k). Note, There is a fine line often when dealing with vcore, stability testing is a must when adjusting this value.

I don't know how old that AIO is but it may have a weak pump? Or as mentioned, need a serious cleaning?
