Cryorig C7 (115TDP) vs i7 8700K delid

[YeuJin]

Node 202 case for travelling etc. Would this work or just overheat?

 

I'm not planning to overclock 5ghz but at least 4.8 or 4.9 without messing with vcore too much and my other CPU choices are 8600k, 8700, 8600.

 

It's just a new build I'm planning and here are the specs if you're interested.

 

MSI Gaming Pro Carbon AC Z370I

TridentZ RGB 2x8GB 3200MHZ (for case glow, might change my mind)

Samsung 970 Evo 500GB m.2 NVME (might add secondary drive for games etc but don't know if 2.5" HDD WD Black is fast enough like the WD Blue desktop size)

Cryorig C7 Copper (115TDP version)

Corsair SFX 600W PSU

MSI GTX 1070Ti Gaming X(From my current PC)

 

Any other suggestion will be appreciated.

The delid will help quite a bit, but the C7 being low profile and all, it's more focused on cooling for an itsy bitsy volume. I have used it to cool a 4790k at stock because it is leagues better than intel stock cooler, but with a cooler that small, your emphasis should be on getting away with lowest voltages possible. An overclock, while possible, wouldn't be phenomenal.

What are your temps under load?

It should be fine with delidding and bit of undervolting.

The Shadow Rock LP or NH-L9i may be better for you.

it was a computer for someone else, so I don't have that data.

Shadow Rock doesn't fit and L9i is lower TDP rated than C7 so.....

Manufacture TDP rating means nothing. Everyone measures differently.  What matters is actual benchmarks. A stock config of NH-L9i preforms nearly identically to a C7 in actual tests while being quieter. Also you can swap out the default thin fan on the Noctua for normal thickness one that will preform even better. The node 202 has the room for the NH-L9i + 25mm fan.

Keep in mind that benchmarks for cooling can vary greatly especially with SFF cases and downdraft coolers. The NH-L9i and C7 perform similarly in general but can trade places depending on the system they're used in. If possible, I'd recommend looking for tests where the coolers are used in the Node 202. 

The C7 fan being close to side panels can cause noisy turbulence and I'd suggest sticking with the stock NF-A9x14 on the NH-L9i to avoid the same issue. This seems to occur in the Node 202: https://smallformfactor.net/forum/threads/node-202-temperature-and-noise-problem.5826/

The stock NF-A9x14 also performs very well and I've only read of worse performance when replacing it with a thicker 25mm fan that isn't higher rpm. https://smallformfactor.net/forum/threads/thicker-fan-on-noctua-nh-l9i.6176/

 

The optimal solution would probably be a C7 CU heatsink or LP53 with a NF-A9x14. It might not perform much better than just the C7 CU but it would be quieter.

Is it worse if I go with Non-K CPUs with C7 CU and a Z370 mobo?

 

Side question though, any regret buying 8th gen now or wait till 9th gen

It's worse in that the multiplier is locked and that the clock speed is lower. If you go with the 8700k, you can underclock it to achieve the same results if necessary.

That being said, it's also cheaper and isn't far off in performance.

Whether or not it's worth waiting depends on how much you value being able to use the system sooner rather than later.

I wanted to ask what did you end up doing and here was my results - sure its not Prime 95 but it is demanding regardless RPCS3. To put things in perspective -
I have an i7-8700 with a Cryorig C7 with a Noctua L9i Fan to fit within a Skyreach 4 Mini's 45mm Cooler clearance. I tried L9i - it ran worse than the Cryorig C7.

 

Basically - The L9i has better fan, but worse heatsink - the Cryorig C7 has a better dense Heatsink, but worse fan.

Stock - I reach mid 90c's running RPCS3 The Last of Us for not even a minute when in-game idling.
When I delidded the 8700 non-k with Grizzy Conductonaut - I cap at 78c running for 10 minutes.

 

Delidded 8700 w Grizzy Conductonaut + TT TG-7 Thermal Paste - before spiked to mid 90c on same Cryorig C7 +L9i Fan = Now it doesn’t touch 80c

modify 15 min it was actually 10min runtime + Cooler clarification

I just delid mine and stick with C7 Cu and the highest was 83C @ 4.4 all cores

@YeuJin I personally would have gone with something like an H60 in that case. Which also gives you more TDP than the C7. It was used on a showcase build with that case using a stock 8700k at 1.4v for a 5.1ghz OC which puts it at 175wTDP (the H60 recommended maximum is 150w) and yet the H60 kept the temps under 90c 86-89c. When they tested the stock chip once again no delid... it kept temps at 58-60c when stress testing... so very good results, but could have been a golden chip tbh.

 

Just some food for thought.

im planning to delid my 8700k after my successful attempt on a 8700 with the IHS loose but instead of a C7 im planning to consider modding the Skyreach 4 Mini by cutting a side panel to increase the clearance that as the stock Scythe BS2 Rev.B = 58mm thats with their pwm 12mm thick stock fan.

Which means that as the heatsink of the Scythe BigShuriken2 Rev.B would be at the inside limit of the case - and the fan extended from the side panel exterior. will stick out - I dont think I need to trim it - however it is probably gonna be sharp as its 1.5mm thick aluminium.

That being said with that cooler I'm expecting it should be able to hit atleast 4.6GHz OC assuming its better than the C7 CU. Emulating RPCS3 Imfamous in Vulkan mode = trips PSU limit as im using a HDPLEX 400W + Dell 330w. Gaming reaches 250w+ at most so naturally with the 8700 stock being pushed to turbo at 4.0GHz-4.3GHz and the RX570 ITX PULSE card would have needed 400w.

Many others added higher parts with it but downclocked obviously to contain wattage in such a restriction of true SFF.

I've considered seeking a low profile CLC but the only way to fit that in the Skyreach4Mini for me is to remove the GPU (mostly tubing limitations) its barely managable in a Dan A4 or another simular one iirc.
