With 92% efficiency that equates to 80Watts dissipation per KW of load, so at 4KW load the PSU will be dissipating 320Watts of heat. This is not insignificant and will definately need good thermal managment. I think the…

Good point! The correct kind of liquid coolants for immersion cooling are typically PFPE (Perfluoropolyethers) such as Solvey Galden, which has a high dielectric strength (i.e. non conductive) is non flammable and non…

You're welcome. I would suggest you avoid using unbranded power supplies, especailly those that do not carry safety marks on them CE, FCC, UL, NEMCO, TUV etc etc. With unbranded PSU's you have zero guarantee that they…

Given your response, I guess you don't know an awful lot about electronics or power supply design. I've been designing off-line switching power supplies for around 30 years. You're making the assumptions that the…

Most PSU's are rated to 100% load at up to 40C and de-rate as the temperature increases. So if you reduce the operating temperature you can drive them a little harder than their rated capacity. You may well get away…

Lottery winnings in the UK are exempt from tax. i.e. ZERO Tax.

Still even at 1TH/s the odds are better than playing the lottery. 1TH With todays diff : 1 in 6,109,236 per day The odds of winning the UK's national lottery : 1 in 45,057,474 per game There's a reason solo mining also…

Agreed. Its likely just another scam.

Math isnt mathing... 12 x 5 = 60 Watts not 100!?

No one said it would be easy.

You could perhaps recycle some of the heat using a peltier device to generate some voltage/current that could be recycled into powering the system boards. I doubt it would be particularly efficient maybe 2-5% at best so…

Water's pretty much out of the question for a thermal transfer media due to its boiling point. Something with a much lower boiling point could be used to carry the heat and this is typically the type of fluid used in…

My solar install is a professional install, unfortunately I've no more space for panels and the battery is a self contained unit that pairs with the install. My only upgrade path is to add another battery unit.

My home runs completely on solar during the day with enough left over to charge the battery and feed back to the grid. Typically it produces on a sunny day something in the region of 32KWH, over night the battery has a…

That doesn't surprise me to be honest. One of my bitaxes hit a 220G a couple of months back. The OctAxe has a best of 18G so far; but then I've not been running it that long. Random is as random does! Energy wise, 180TH…

The pricing was taken from the originators website https://ixtech.xyz/products/nerdqx-8th-bitcoin-home-miner As far as I'm concerned buying stuff off Aliexpress is a no go especially for value items >$100. I bought a…

You're quite right. I think we've already surpassed that point for home mining to be in with a reasonable chance. Once I set-up my new OctAxes I'll be running around 480Watts for 30TH/s thankfully most of it is off…

This NerdQX device doesn't make a lot of sense to be honest especially at its price point. I recently acquired a NerdOctaxe V3.1 which runs 10TH @ 160W and it'll happily do 12TH @ 198Watts ~= 16.5W/TH if you don't mind…

That thermal glue you are using is really poor thermal conductivity. You'll basically loose most of the benefit of a larger heatsink due to the poor thermal conductivity of the glue. If you're going to glue heatsinks…

Perhaps, extra pricey?!
