If you let the CPU run with an an TDP of 95W it will be easy but in default mode it will run with 200W and you need a very big heatsinks or water cooling solution. So setup "max long power duration" = 95 in UEFI/Bios and have fun with a cool CPU.

I am aware of that and it's definitely a possibility but buying a 9900k for £600 to restricting the power to 95W is not worth the price... It would be a much better option to buy a 8700k a delid it (If voiding warranty is not an issue). It's nothing agaisnt Dan cases, in fact, I haven't been this excited for a case in a long time and I will build my next system in one, the problem here is Intel... But we asked for solder, now we can't complain that we have it...
Do you have any information if the black ridge will fit the z390-I?
If you mean the Black Ridge than it should, I see no reason why not, both case versions have the same dimensions but wait for its release and some reviews since we don't even know if it will fit the Asus Strix z390-I motherboard
I was meaning the aio mount for the 120mm aio coolers in the v3? I'm using a gigabyte 1070 mini and would like to mount a corsair h55 or h66. Maybe I can just do that with zip ties?
I'm happy with the 9900k at stock TDP to be honest. I can reach and all core 4700 mhz which is advertised speeds. My games run smoothly. Overclocking just isn't worth it in general especially in such a small case. Double the wattage, increased vcore and cause crazy heat all for minimal performance gains. With my ryzen 2700x I could barely hit 4000 to 4100, runs cool at stock 3.7 ghz but just felt slow.
Well, don't take me wrong, if money isn't an issue and temps aren't going crazy, the 9900k at stock is still the best option to buy and I do plan on buying a 9900k for the A4-SFX V3 in the future, but I'm considering delidding it, even tho it's risky. What temps do you get with Prime95 with the 9900k at stock? And are you using the 92mm AIO?
I think the 9700k is the sweet spot basically cost the same as a delidded 8700k. I do have the asetek cooler but I haven’t tried it because I need custom cables and lpx ram. Please see my prime temps in my previous post with the 9900k running a cryorig c7 cu with a noctua fan.
Urgh... Yeah, I already saw the prime95 temps previously, it was actually me who asked for them! I'm sorry, my bad!
Did you end up measuring the Z390-I to see if the black ridge would fit?
Think I'm just going to wait for the black ridge to arrive. I just ordered 32 gig of corsair LPX ram and PSlate custom cables so I can hopefully do some testing with the Asetek shortly.
You could put a notice in the Buy/Sell/Trade forum to try and get more traction. Please note the rules for doing so in advance, however.
Dan any ETA on when Windowed panels may again be available for the A4?
@Tazpr: Sry no
@All:
What I pray in many threads currently is how to deal with Intels TDP because many customers are not happy with their CPU temps.
I recommend to setup "Max Long Power Duration" = 95W or lower in UEFI/Bios. This will let your CPU run in Intel specs and it will be so much cooler. I tested it with an 8700k and an L9i. Here are some results (Prime95 8k):
Auto (125W) = 100+°C /6x 4,3Ghz
95W = 91°C /6x 3,9-4,0Ghz
80W = 80°C /6x 3,7-3,8Ghz
65W = 72°C /6x 3,5-3,6Ghz
100W + undervolt = 87°C / 6x 4,1 -4,2Ghz.
I know you are losing some MHZ IF ALL CORES ARE IN USE but the performance loss is very low (~8% depending on TDP value). Keep in mind these values are for Prime95 in games the temp will be 10°C lower. So with the Alpen Ridge and a 120mm bottom fan you can expect the following temps:
CPU @ TDP 100W + undervolted -0,1V = 6x 4,1 -4,2Ghz.:
Prime95 ~ 78-82°C
Games ~ 68-72°C
If you follow this guide for the 9900k I think it will be also possible to have good temps on this CPU.
UPDATE: On Computerbase.de I found an information about the performance loss on 9900K TDP no limit VS TDP 95W limit. The avarage perfromance loss is 1,2% in games for FPS and 2,9% for frametimes. In applications the avarage performance loss is 8%.

Has anyone tried to see if a 2070 will fit in the A4? Lengthwise I think it’s fine. I contacted EVGA about https://www.evga.com/products/product.aspx?pn=11G-P4-6391-KR
They said it’s approximately 52-54mm wide. A4 case spec says 45mm, but I can’t imagine it’s wider than a EVGA 1080ti sc2 which is on the compatibility list.
Any insight is appreciated.

which model of 2070? A4 only supports dual slot, nothing wider. So if the cooler is at all wider than 2 slot it will not fit.
So with Max TDP set to 95 on my 9900k. Undervolt of -100 mv in the bios. Turboboost power max 95W. Getting 86 with prime95. Vcore is 1.225 V. However I don't know why but my cores only go up 3500. Maybe I'm hitting a power limit. I'm happy with this as I boost up to 4700 during gaming or other applications.
