They often go by MicroBT for short. They have a distribution partner overseas called Team Pangolinminer. I got this unit as a sample from Team Pangolinminer for this review. (www.pangolinminer.com) Just a reference link. The WhatsMiner M3X operates on its own with a built-in controller board, so you don’t need a separate controller to use it. What sets this miner apart from the earlier M3 model is the 2100W power supply that’s included. This power supply is known as WhatsPower P5. You will need a mains voltage of 180-240V to operate it, as it won’t function in a 110-120V setup. This built-in power supply design sort of reminds me...

They have a spring sales campaign and miners (in stock) are for sale for $850 USD per unit at the moment. Link: https://pangolinminer.com/product/m3x-stocked-batch-ii/

Great review as always, best formatting I’ve seen in any Bitcointalk post in a very long time. What are the noise levels like on the M3X compared to a miner like the T9 or S9? I imagine the fans are more powerful as they have to force more air through the heatsinks to dissipate the greater than 2kW of power the miner consumes. The placement of the PSU on the miner might also have space complications if the miner's placed in a cramped spot. I wish the M3X was priced slightly lower to compete with the T9+. Seems like Pangolinminer have the right idea with the miner, but the T9+ and PSU bundle makes more sense to buy after factoring in potential coupon discounts, and it even pays more after electrical costs for most people (according to Nicehash at my electrical rate of $0.065/kWh and $0.10/kWh). I’m personally interested in what Pangolinminer might be capable of doing in the future with a smaller node like 16/14nm or something less given what they’ve been able to accomplish at 28nm.

You can at least tell people that this a referral link. Anyway, here's a $30 discount code that appears on their website "COPACABANA". I like the price but the efficiency is not too great.

Yes, good point. It is a referral link indeed. Thanks for sharing the coupon code. Thanks Leo.   Noise levels are pretty much the same as with T9 or S9, then maximum speed for the fan is about 6000rpm. My unit is usually runnin in about 4000-5000rpm area. The power supply unit cooling fan noise is a high pitched sound, and it is more aggresive noise in my opinion than the miner fan noise.

Interesting, cool to see that WhatsMiner developed a miner that can dissipate so much heat and keep the miner cool at 80c with fan speeds that are sometimes lower than S9s! I imagine the PSU fan being loud won't be a big issue as these are industrial miners anyways, usually the miner itself makes a somewhat high pitched sound I my experience. What sort of ambient temps are you running the M3X at?

The intake air is maybe 10-15C now in the evening, it is early spring time here in Finland and I have it located close to an opened window.

i didnt get it why crap like this miner is produced. we got one in the office some weeks ago. the unit was getting fckin hot and i couldnt touch the housing otherwise i get burned. 2400W on the psu side..crazy...

hello , i am planning to buy 40 m3x i will separate cold room and hot room but i did want to know if 2 air conditioners with 18000 watts can produce enough cold air ? cold room size is roughly 5 x 3.5 meters and hot room about 0.4 x 5.5 meters and hot room height is 3.5 m i think it is really hard for two air conditioners to supply enough air for 40 m3x or i just need to buy 2 large fans with filters to bring outside air to inside my region climate is like 27-37 in summer and spring and other seasons  5 - 25  and i should just use 2 large fans  plz note that i have researched enough to buy these so dont suggest me another miner or the price of power is ok i need help with cooling issue

Don't be stupid. Do not use Air Conditioning in your mining farm. Good ventilation, good airflow, those are the key things to remember.

Hello I wanted to know if they have Certificate of Conformity of the m3x?

hi can u please tell me difference between m3v2 , m3x and m3 v2.2 ? looks like all of them has same appearance how can i distinguish them ?

I have not seen it available. Please ask the manufacturer. I don't know. Have you asked this question from the manufacturer or some of the resellers?

i just looked at asicminervalue web site https://www.asicminervalue.com/miners/microbt/whatsminer-m3x here it is written m3x and m3v2 is the same but once i asked reseller about m3 v2.2 he told me that he bets that v2 and v2.2 is the same and there is no difference but today i saw he is advertising m3 v2.2 ( lol ) btw i was checking my miners (m3x) chips temp it is about 80 degree and fan speed is 3900 rpm and 12.5 TH/s weather is about 15 degrees  , is it normal ? now weather is cool in my region but after 2 months  it will get hot like 30 - 35 degrees do u think in the same circumstances if my fans in 6000rpm( max speed)  can they keep it cool in the summer ?  and generally what temp should be the chips ?
