ekwb. Delta2 tec

gerry1964 · 30 Nov 2022 at 17:28

Hello everyone. Please can I ask if anyone is using the new version released Aug this year of the Delta 2 tec ekwb. Peltier?.
I saw the recent Der8bauer video 13900k. All 8 performance cores at 6.2ghz in regulated ambient mode so kept above condensation point. Battlefield 2:etc
Der8bauer. Was using a mo ra 420. Just to cool this tec block.

Ok I wonder if the rated max 210 watts would allow unregulated mode for all 8 cores using this setup.

Built on a test bench a z690 tachyon insulated etc it's just if the unregulated mode could do all 8 p cores or would you be limited to one core.

Also could the ekwb Delta 2 tec be used in a direct die cooling method to increase its efficiency obviously all around the exposed CPU die would be insulated.

Plus the mo ra 420 cooling the ekwb Delta 2 tec.

So the example would be if you made this tec as efficient as possible could this be viable or is the limit of 210 watts going to be the limiting problem?

Really big thankyou for your replies.

Pretty pointless, just use normal. Water cooling with a big rad. The extra few c isn't going to help. The tec will get overwhelmed under any decent load.

Der8auer was using it 13900k all 8 cores 6.2ghz in regulated ambient mode kept just above condensation point to run battlefield and other games that are respectable real world loads. It may get overwhelmed running one of those benchmark programs I dont know.

If anyone has this I just wondered about unregulated sub zero mode with insulated motherboard on a open air test bench.

All 8 cores what temp and what overclock.

Id wait for an updated model without compromise. 400W minimum that can handle anyway you use the CPU. 210W limits the way you can use it.

gerry1964 · 2 Dec 2022 at 11:15

Yes very good point I wonder why this 2nd generation version with its 4 separate peltiers is still limited to 210 watts. 210 watts is like you say limiting this tec.

Will there ever be a 400+ watt version ? 400 watts of cooling would cause a crazy amount of heat in the loop.

OC2000 · 3 Dec 2022 at 12:26

No desktop CPU right now uses 400W so it wouldn't need to output the amount of power. The 13900k can reach over 300W though. You would definitely need a decent cooling setup for it, but at the price of the Tec you would probably have one anyway.

But we only play an old game that is using no more than 120watts. So with a friends mo ra 420 for the ekwb delta tec only that would easily take care of any heat. Plus we will go direct die so the ekwb 4x peltier in the cpu block will cool much more powerfully because it's in direct contact with the cpu die.
We will never go near a stupid benchmark program or a huge demanding game like warzone.

I reckon that we may be able to get 6.4+ghz if we use unregulated mode and even have another loop cooling the ram etc

Yes 210 watt ceiling but we start from a very low watts usage and the cooling etc

Yes condensation may happen but we will research every thing that we can do to protect the motherboard

You may well start from a low wattage usage, but when you have to increase Vcore to hit over 6.4Ghz.............that wattage will only go upwards.
If you intend to use the EK in unregulated mode, you should fully expect to see condensation on the mobo and should mitigate that as a first priority. I've always found that covering the entire mobo with a few coats of "Liquid Tape" always worked during years of benching with LN2, Cascade and Single Stage.

gerry1964 · 4 Dec 2022 at 10:34

Thanks for your replies very interesting. That liquid tape which is the best and does it last?
Also when condensation forms is it still very possible something will short out even if I coat the whole motherboard. If this is the case then we may not go sub zero. Also your point is interesting about vcore so even if you have great cooling the same value of vcore is needed to reach the high clockspeed?

Also is nail varnish the only thing to use to coat around the die to protect all the capacitors etc?

Thanks for your replies

Once you have made the decision to go sub zero, you have no choice but to coat the entire mobo top and bottom with liquid tape (that includes capacitors).
It also applies if you are going to be running below "Dew Point". At sub zero temps the mobo gets very cold and any ambient air hitting it will cause condensation, it's physics lol. Nail varnish is nowhere near as good as liquid tape and also will never come off of the mobo, liquid tape can be peeled off.

Vcore quite often does not need to go up for small overclocks, it certainly will for a meaningful overclock. But i'm talking from the perspective of years of single stage use at a constant -50c under full load. Your planning on using a pelt, which i very much doubt will even get to -1c under a normal load.

The best liquid tape comes from here: https://www.sotabeams.co.uk/liquid-electrical-tape/
Once the mobo is coated properly, it will last until you peel it off.

Thankyou -50 wow. I just wondered if that liquid tape is used on the cpu around the die to delid and when delided ? Liquid tape top and bottom of motherboard but also on cpu when deciding or is nail varnish best for deliding ?
And very sorry to keep asking but if we liquid tape top and bottom of the Aorus z690 tachyon motherboard and use -1 degrees on cpu physics laws condensation will occur. Will there still be problems with shorts ruined circuits after protecting the motherboard?

If yes no matter what protection precautions we implement we are guaranteed problems because of condensation please tell us because we wont use -1 because we do not want ruined motherboard.

Thanks for your replies.

If we take all precautions and the motherboard is coated properly etc and it's 100% no problems and is safe then we will use -1 degrees.

I mean a properly insulated electrical cable is no problem is this coating of the motherboard as certain as that?

gerry1964 · 4 Dec 2022 at 21:01

Is one (4 FL OZ) bottle of the "liquid tape" enough to coat a whole motherboard?

And is it ok to use this around the die to protect the capacitors when deliding? Or will it damage them when you remove it?

Thanks

One bottle of liquid tape should do two mobos.
No, don't use in the die when de-lidding. The EK comes with a "shroud" that seals the Pelt to the mobo, it should form a airproof seal over the entire socket area.
