delid and apply cool laboratory liquid pro to the silicone and ihs also scrub down the ihs with the brillo pad and use thermal grizzly on the his to copper heatsink and scrub down the top of the ihs and you will get the best temps. i did that and i got thermal take 360mm water 3.0 with 6 static pressure fans and with pump at 50% temps never break 60c under occt, prime 95 small fits gets about 60-65c but that is a 200 dollar water-cooling setup is a little overkill but the delid and the liquid pro really makes a difference with the temps also thermal grizzly kryonout is the best thermal paste out there i think i was a AS5 user for 10+ years but i just recently switched to thermal grizzly and it works great. I recommend you delid tho its optimal and that liquid pro liquid metal stuff really works awesome

Not to belittle you but did you remove this:



This is a common thing people overlook when having troubling CPU temperatures.

No plastic there. That would certainly put a damper on cooling!

Based on what I've read, there is a wide range of temps for the Kaby Lake, and this one runs hot!

It's reasonably acceptable after decreasing all the voltage, and re-applying thermal paste.

I'm not thrilled that the water cooler only has 2 screws to hold the block in place. I've never seen one without 4 screws. I wonder if a different cooler would work better, but I'm not about to drop another 120-150 to find out!

Sadly, not all cpu's are created equally.


Thanks!

Arctic Silver is not your best TIM. Get something better.

Your idle temp is good for that chip. Consider more aggressive pump and fan curves.

Is there a large difference in temps amongst cores while testing? >10C between coolest and warmest cores is outside Intel specs and can cause instability.

The 7700 is a hot chip. Some are hotter than others, but they're all hot. Consider a delid or an i7-6700k.


Temp differences of 10C do appear in the spikes, but the overall data path is not consistently showing that significant difference in cores.

What would you recommend for temp settings? Realtemp was very similar and AIDA64 were pretty consistent with OCCT temps. Speedfan on the other hand was significantly lower all the time.

Also, I've not lowered the PLL OC voltage yet. I'll try that when I get back home.

Some hotter chips overclock better by bumping BCLK to 110 and adjusting Core, Ring and Memory speeds accordingly. Temps across the chip are more stable and individual core temps will generally be lower.

Pay attention when adjusting PLL voltages. It's one thing that will kill your CPU if allowed to drift too high.

Not sure what you're asking me about temp settings? There's CPU temp and package temp. Some software report one, some the other. I believe these are all approximations based on power usage, anyway, so it's never going to be an absolute.

I'm guessing you're asking about fan/pump settings. I never let my pump run at less than 50%. I bump it up for the 36C-55C range and bump it up to 90-100% at 70C. That's what works with my machine, because those ranges are where my light-use, medium-use, and heavy-use temp ranges fall. Fan curve steps do not exactly mirror the pump, but overlap. That's just how I do it; you'll need to experiment and come up with your own curves that work for you.

As for temps, I offer you my own i7-6700 box for comparison, I just played 30 minutes of Fallout 4 @ 4K. My CPU @ 4.6GHz, Ring @ 4.6GHz, Memory @ 3000 XMP. My highest Core temp was 72C. My idle temp is 29C. My VCore max was 1.39V (I've been experimenting and had it set to Auto). If you continue to see high temps, you have a decision to make. Lower your expectations, upgrade your cooler, or swap out your CPU.

I saw you mention the cpu block only being held on by 2 screws. From looking online it seems the intel mounting should use one screw in each corner for a total of 4, but the amd mounting uses just 2 screws, one top one bottom. A picture would help out tremendously.

Here is what I have. You can see 6 screws. The 2 screws in the middle are what hold the cooling block in place. The other 4 screws (in the corners) hold the silver rails to the motherboard.




Also found a random youtube video, at 1 min in, there are only 2 screws to mount the block. Is that intel or AMD?
https://youtu.be/KSEPBEv1nYY

But in this video on youtube, at 11 minutes in, there are 4 screws.
https://youtu.be/-NSIlh1zg_M

And this video 40 seconds, 4 screws
https://www.youtube.com/watch?v=yL3TbOEFnnk

Something is screwy here (yes I went there)

Here is the pics from deepcools website.
http://www.gamerstorm.com/product/CPULIQUIDCOOLER/2016-04/1286_5091.shtml
Only 2 screws.

Here is the install guide, it says same mounting system for both AMD/Intel, 2 screws
http://www.gamerstorm.com/download/pdf/Captain360EX.pdf

I'm really confused now... I have emailed Deepcool. Hopefully they can give me a definititve answer on how this thing is suppposed to be mounted, but it certainly seems like their own pdf install guide says only 2 screws. Maybe different generations of the cooling system?
