I'm buying the thermal paste arctic mx-4, 20 grams, can be enough to change in 4x antminer s5? I want to change it in all the miners

no no cat, my system and put it down in the cellar

now and reassembled, and the small 4-pin connector that goes from the blade hashboard
My guess is that a metal object hit the controller board, causing a temporary short circuit between two exposed pins on the controller board (or on the Beaglebone Black). This would have pulled a large pulse of current through that small 4-pin cable, causing it to get scorched. Do you have a cat?

I reversed the blades and now it works, but the problem that remains in the blade where it goes attacked the controller remains burnt, so I should have a new blade guess right? but the thing that I do not admit is that I have to pay as well the Italian customs to get back garanzia.basta write a piece in the declaration hardware parts replaced under warranty because the product has already been paid previously
I got my parts with DPD direct From China . No VAT.
artic mx-4 and not exceeding mx-2?
MX-4 is more expensive than the MX-2now and reassembled, and the small 4-pin connector that goes from the blade hashboard
This is the controller's power cord.

marvykkio, can you show us a picture of the burnt attachment point? Is it on the data cable, the PCIE power cable, or the power cable for the control board (that's the small 4 pin cable that's only attached to one hashboard)?

now that I disassembled the miner I have to find a good thermal paste to put on and dissipate heat, which pasta you advise me? the best 
Something is wrong. An Italian is asking people in the rest of the world for advice on pasta.

I have several of those S5's and I'm experiencing a huge difference in power consumption.
S5 running at 350M = 630W
Why am I not getting the 590W with the default frequency of 350M?
I'm using EVGA G2 750W power supply. Measuring power using a Kill A Watt.

Do you have a multimeter? Check the output voltage of your PSU. That voltage makes a bigger difference in power consumption than frequency does, actually.
For CMOS ASICs, power consumption is roughly proportional to clockspeed times voltage squared.
Since hashrate is proportional to clockspeed, and power is also proportional to clockspeed, that means that efficiency (or J/GH, which is actually the inverse of efficiency) is independent of clockspeed as long as voltage is kept constant. Overclocking S5s will not make the efficiency worse. Only overvolting will.
I have some S5s in our DC that use about 570 W of AC when run at 361 MHz. The trick? We're tweaking our PSUs to output 11.7 volts (open circuit). We also have a little trick with the cables that I might explain sometime when I have a free moment.
Kill-A-Watts are useful and cheap, but they are not accurate. I often see 5% to 10% discrepancies between our Kill-A-Watt and our Dell 0.2% accuracy metered PDUs. Kill-A-Watts get really confused by AC harmonics and non-sinusoidal waveforms, and computer power supplies have a lot of that.
Also, Bitmain does their testing on 230V. If you're using 120V, you should expect 3% higher power consumption.

this morning I packed all the miner, and reversed the blades, and I reassembled everything and went back to work, the problem is gone, now it works again, but the problem that remains is that part of the blade is not working so if you were to burn well this the miner does not work anymore. What do you think I should do? bitamain should send a new blade, but I think this is impossible, that I definitely want to send him the blade, or all of the miner to review it, and spends much time in addition to spending more money to send the miner from italy up in china. what should i do?
I sent all my broken Antminer S5 parts to Bitmaintech (Serbia).

kill a watt running in AC mode, so it's different.
i think using evga g2 750w is enough for your s5
i have 3 ants5 using seasonic 750w, acbel 900w, and xigmatek 1000w, all running 24hrs/day
no problem at all, but the seasonic 750 flow is more hot between the others.

is this after the psu? i think the 590 is on the 12v line.
you have to also factor in the psu efficiency.. on a 750w psu you are at like 85% and most psu are most efficient at 50-60%
I should have probably got one of those 1300W, right?
I think a 1300 is overkill. I have had good luck with RM1000's.
I love them have a few of them on a few different miners, including a S5. If you want even better you can go with platinum PSU.
Which platinum PSU would you recommend? The EVGA 1000 P2?
