Should I delid my cpu??

Hi, guys. Just did some testing and found something weird in my loop that needs answers for.

I've got a 4690k, 2 gtx980s, a 360mm rad, a 480mm rad and a D5 pump in the loop.
Both rads are in push pull with the corsair sp120s. So I basically have 7*120mm rad space.

Here's the weird thing, if I only run 2 fans in push pull and turn off all the other fans completely on the rads and run occt large data set, cpu temps only go up 2 to 3 degrees compare to having all the fans at max speed. Try both 4.5g at 1.28v and 4.6g at 1.34v and get similar results which are quite high at 67c and 75c respectively with all fans on 100%. Changing pump speed does nothing temperature wise. It's weird to me as I see a lot of people using 240mm aio coolers with lower temps at similar voltages...

Am I simply overloading the cooling capability of the cpu or is there something wrong with my loop? How do I test if my radiator or cpu block is working properly? Will deliding the cpu help much? Thanks...
 
Quick answer is - just adding loads of rads wont just bring your temps down.....

67C maxxed out with OCCT is spot on because 1.28v on a 4670k is actually loads of volts. I have a 4770K that will do 4.9ghz at less volts than that

Thanks for replying

Do you mean that the problem is the cpu itself not being able to transfer all the heat to the loop rather than the loop having trouble dissipating the heat transferred? If that's the case then delidding the cpu seems to be the only option if I want to keep the settings with lower temps.
 
It means that you've lost the silicon lottery. The temps are too high, because the voltage to keep the oc is too high because you got a "bad chip" Deliding could damage the cpu and give you maybe 3-5C lower temps, you shouldn't do it

Your CPU is acting perfectly normal for those volts matey
 
I must say I am rather scared of the idea of taking the lid off.

I've seen many people just break the CPU delidding it and a few failures quite long after the delid was done.

It's certainly not a reliable means IMO.

If its any comfort to you, I have delidded my 4790k. I don't use any extreme overclock and sit comforatably at 4.5ghz. However while I can't give you an exact temp drop due to vast changes in my setup. Overall my temp of the CPU has dropped by 18C. But this is because I moved from a pc case, to my desk build with a high amount of airflow, better rads, fans, delidded with CLU, new CPU block etc.

I'll try and post some stuff tonight for you if it helps.

One thing for sure though, is that the razor blade tactic to remove is the best option. Also if you "nick" the edge of the CPU it will still work fine, but thats not a reason to be careless. Mine has a deeper cut than this one. Some like to put nail varnish over the chips to protect them from the CLU but I haven't bothered since if you apply it like it should be done, there will be no overspill. I actually used a credit card instead of a cotton bud :)

Thanks for the info. The vice method seems easier to me somehow since a few kicks get the job done, not sure if there is any drawback though...Also is the coollaboratory liquid pro or ultra the "go-to" choice when it comes to delidding cpus cause I've also seen stories of it hardens over time and cause temp issues.

Also assuming about 10c drop in temps, I'm not so comfortable pushing it further to 4.7+ghz at 1.4x volts considering I've got a bellow average chip most likely. I might just kill it which makes no sense. I mean considering the small headroom of overclocking and performance gain, I think I'll just live with 4.5g until next upgrade.

Informative reply though, thanks...:)
 
my 3570k has had the same CLU on it since the chip was first announced it could be delid for improvements, hasnt had any issues in temps at all. CLU is a derivative of Gallium so its an impure form. Maybe my science fails me, but impure gallium does not harden.

regarding the 1.4v, im glad you saw sense and resisted doing it. I don't feel comfortable with anything over 1.3v.

Others can correct me here if I am wrong but if its for gaming, you won't see any benefit over 4.4ghz unless you are benching stuff.
