I have a 7700k which runs pretty damn good. I can run at 5.2Ghz all day at 1.38v, have run stress tests for hours and had no crashing, the CPU does get rather warm however (up to around 90c) now that my cpu is out of warranty would it be worth the risk of delidding it ? I have the thermal grizzly compound and everything ready to go. I'm just abit concerned if it's worth it or not.

Cheers Mitch
 
What is your CPU temperature after a gaming session ? Stress testing a CPU will produce more heat than when gaming. If its around 60-70c after playing a few games I dont see the problem. Not knowing what you have would it not be better to invest in better cooling other than that as 8 Pack expertly said "no need..."
 
CPU temp is the result of many things, like temp of airflow into cooler vs room air temp, what cooler is used, voltage, etc. 90c is too hot for me. My systems in normal use never go above 70c. I don't want them to go above about 75c, maybe 80c even when stress testing. But if your daily use and gaming temps are below 80c (bettter if below 70-75c) you are good to go.

We really need to know what your system is .. what case, how many case fans & how they are setup, what cooler, what the air temp into the cooler is and what the room temperature is going into the case. if your CPU is running 90c in normal use it might not need delidding, but just to get case airflow working properly.

If you are using an air cooler (even water cooling to some extent) and your room is 25c with poor case airflow the air temp into cooler could easily be 40-45c meaning your 90c CPU temp is 30-45c delta .. meaning your cooler is working very well, but your case airflow is horrible and heating up the air going to cooler way too much. It needs to optimized so the air temp into cooler is 28-30c which will lower your CPU temp 12-15c to about 45-48c delta which is 75-78c actual and a good max temp.

With air coolers every degree warmer the air into cooler is basically translates into a degree hotter the CPU is. Water cooling while not 1:1 is still 1:2-1:5 depending on how good the water cooling system is .. and takes longer max load to reach max temp because all coolant need to reach it's maximum temp. Air coolers reach max in a couple of minutes (assuming case airflow temp into cooler doesn't change) compared to water cooling taking 15-30 minutes.
Here is link to basic guide to case airflow and how to optimize it.

I have around a 22c room temperature usually, obviously weather can dictate it. My case is a Corsair obsidian 900D I have air coming in from the front and the bottom with 3 fans on the front and 4 fans on the bottom n a it blows through at the top and the back with a 140mm on the rear of the case and 4 120mm fans at the top of the case. I have a Corsair H100iV2 cooler. The temps whilst gaming according to CPUid doesn't go above 85c. It idles slightly above room temperature. My apologies it was kinda stupid asking the question without giving this information :p it might be note worthy that I have my GTX 1080 G1 at 2000MHz also, and my ram is at 3200mhz as per the rating. I'm not confident in overclocking my ram so I just set it to it's rating.

Where is H100i V2 mounted?

I am not a believer of CLCs .. hate them with a passion. Reality is H100 is not as good as top tier air. In fact original |H100 against Silver Arrow SB-E was about 1c cooler making about 3 times as much noise, and Silver Arrow SB-E Extreme (2500rpm hi-performance fans) was about 8c cooler at similar noise levels (1db louder .. human ear needs about 3dB to hear a difference).

Silver Arrow SB-E, Silver Arrow SB-E Extreme vs H100
I7 [email protected] Temperature in Delta
Cooler . . . . . . . . . Delta . RPM . RPM . dB(A) . Fans
H100 . . . . . . . . . . 41c . . 2500. . . . . . . 55 . . . . 2x
SA SB-E. . . . . . . . 42c . . 1000 & 1300. 38 . . . . TY-150 & TY-141
SA SB-E Extreme . 34c . . 2500 . . . . . . 56 . . . . 2x TY-143​
H100 is 1c cooler than Silver Arrow SB-e but makes more than 3 times the noise doing it
Siver Arrow SB-E Extreme is 7c cooler with fans making similar amount of noise as H100 does.
PC-Cooling video review above data came from:
​

H100, H100i H100i V2 are all same basic Asetek cooler and Asetek as made almost no functional changes in pump or radiator even though ther have been several versions.

Hard to say how much improvement delidding will give. How old is your H100i V2? If more than a year the pump may not be moving as much coolant as it should. After a year of hard use CLC performance tend to start dropping and many fail in less than 2 years of high cooling load .. few live more than 2-3 years at high cooling loads. Do you have access to a different cooler to test with? Can you monitor air temp into cooler as suggested in link to airflow guide I posted before? Air coolers are about 1:1 ratio of air temp into cooler increasing to CPU temp increases. CLCs are 2-3:1 ratio air temp into radiator to CPU temp. Custom loops are usually 4-5:1 ratio, some even higher.
 
The cooler is mounted in the top of the case.

LOL how come? mine seems to work grand, I would loved to of done a custom loop but the all in 1 worked out at a better price/performance ratio.

All of my rig is about a year old, give or take a month or so. Unfortunately I do not have another cooler to hand to try, but if I change it, I will be going for a full custom loop.
Im not entirely sure how to check the ambient temperature in the case but as stupid as it sounds, the air coming out is actually cooler than room temps

Is CLC mounted as intake or exhaust?

I posted a link at bottom of post #4 about airflow. At the bottom of that is a pic of remote airflow monitor for case airflow temp and tutorial of how to set it up and use it.

Yeah, it does sound stupid. Because it is against the laws of physics for the air coming out of case to be cooler than room. When CPU is 90c how warm is the airflow coming out of radiator? Is one pipe on waterblock/pump hotter than other? If it isn't easily much warmer than air going into cooler and pipes are same temp your CLC pump isn't moving coolant. A CLC working on high heat CPU for a year and going bad is rather common .. and a big part of why i hate CLCs. They cost more, last only a fraction as long, make more noise, and require the expense of a new cooler when they fail. Like I said before, you can get a top tier air cooler for £50-70 that will out-perform most CLCs and last many times as long. ;)

Custom loops work better than air cooler, but make sure you have very deep pockets because you can will easily dump £500 into one .. or maybe twice that to get what you want. Be careful what you get because while there are many very good custom loop components many are almost as junky as CLCs.
 
The CLC is mounted as an exhaust.

If mine fails I would just do a full custom loop, aircoolers are old news :P

Which is the best branded custom loops to go for? i hear EK are a decent brand aswell as alphacool

Several brands are popular but you can also mix and match the parts that perform best and/or look best. One word of warning, match your fittings and tubing to the same brand. Small variations in tubing dimensions can make things very difficult when using a different brand's fittings.
 
AHH yeah well that makes sense, I'm a machinist and the material we get usually has a tolorance of +/- 10%. I can't imagine that being any different here

+/-10% of what? When I was a machinist too many years ago to say finish product tollerance was +/-0.001 inch up to +/-0.0001 inch .. 1/10,000 of an inch. That was machining manually, not CLC or computer controlled but obviously shop was always at same temp .. because even a couple degrees difference changes measurement on steel and even more on aluminium. ;)
 
No, when you buy the material it comes +/- 10% machining I usually have to work to +/-10 microns, also different grades of ally changes size, hence the gauge room been air conditioned :P
 
Ah, now it makes sense. Yeah, computer machining does way closer tolerances than hand machining could even dream of. |Yeah, I remember I was re-grinding engine crankshafts and had like 100 done on throw setting on floor and we got a cold snap. Owner came back and started measuring them and started chewing me out about them all being under-size. I told him to take a couple back to his office and let them set for 3-4 hours before he made an even bigger fool of himself. At the time I didn't care if he fired me because I had lots of offers other places. ;) He came back that afternoon and apologized. :p
Floor level was about 5f colder than it normally was .. which was why I was doing other machining that wasn't as critical until cold snap ended.
