Delided 7900x 4.8, what temps should I See?

[rondocap]

So I picked up the x299 oc formula, and got a second hand 7900x that had been delided by SL at 4.8ghz, 1.25v. Using g skill 3200mhz rgb ram.

Stock, getting in the 70s during load on cinebench and some prime 95 26.6, so ok.

At 4.8 and 1.25v, it will go as high as 94c.

Obviously it was more of a test, I know the below cooling is not enough.

My cooling is an issue, running EK evo block, D5 pump, 1850rpm vardar fan, but this system only has a 120mm PE EK radiator due to space.

What temps should I be seeing with proper cooling?

Any of these will help?
1. Second fan for push pull
2. Add a second 180mm radiator, biggest I can fit
3. Any bios settings to improve heat

I also have a second system with 5ghz 8700k delided by SL, but with an EK open loop and two 360 radiators. At load I get 72c at 5ghz. How would the 7900x at 4.8 do in this system? May switch them around.

Would the 2 360 rads decrease 10-20c? Also consired adding a 480 rad to this 900d case if that helps.

Your current temps are consistent with everyone else's I've seen who haven't gone to seriously better water cooling.

I just have a Corsair h115 280 setup to push on my delidded 7900x 1.20v @ 4.4Ghz. The 280 AIO is not near enough. I can't push it past 4.5ish (plus it's getting hot this time of year) because I need to bump the voltage up to get it stable, but pushing the voltage pushes the temps even faster and it starts to throttle like crazy from the heat. Yes I know I need better cooling solution, but it's what I had available when I built it. I don't feel like spending another few more hundred to get 400-500mhz

I have upgraded my cooling, here is what I am running and results:

7900x with OC formula motherboard, OCed to 4.8ghz at 1.25, delided, 3200mhz trident z ram

1080ti is also watercooled in this loop:

Two 480XE Ek radiators, the thickest ones - with the top rad having 8 fans in push/pull, thermaltake premium plus RGB fans around 1500rpm, and bottom rad in push only.

EK Monoblock for the CPU and VRM area, and of course D5 EK pump.

Prime 95 1344 I get around 90c after an hour, but it's always stable.

The monoblock likely raises CPU temp slightly since the VRMs are tied to it, as my previous setup with just an EVO EK block got slightly lower temps.

I think I am pretty much at the limit cooling wise in terms of water for this CPU, doesn't seem like adding more radiators or fans really lower anything. So this chip really just runs 90c at full load when 4.8ghz.
