Change thermal paste with Artic MX-4 for Antminer S5

[marvykkio]

Today I changed thermal paste on Antminer S5, taking advantage that I have to get a pcb I wanted to try a single pcb waiting comes the other,
Well I can confirm that the thermal paste that uses bitmain and quite good, the only difference I noticed with MX4 artic, and which maintains a temperature standard 46 ° celsius, here in Italy is 11:05 AM, outside temperature about 30 ° miner put it down in the cellar with a temperature of 22 °, and about 25 minutes already working with frequency defoult 350M, and the temperature is always the same 46 ° celsius.

You put too much thermal paste.

[marvykkio]

I've noticed that I had put too

what temp u had before (stock paste ) with the same settings ??

[marvykkio]

before arriving even at 50 ° / 51 ° Celsius, and now stable 46 ° / 47 ° Celsius

thank u. Also u can put heatsinks to the chips that r to the oposite side of the blade (backside )

also in mho u used a lot of paste...

Now I ordered the fan delta, delta 120 mm 12 cm PWM fan tfc1212de 252CFM vs PFB1212UHE, let's see if I can lower the temperature even more, here the summer and around the corner, we have already 30 °, here we come to the end of July 42nd, August, so I prepare

I do not believe much in these small heatsinks to be put on the back

i use 2 noctuas mf-f12 3000 industriasl ppc.i have 4celcius down

[marvykkio]

ejjeje the noctua is the best, but they cost a lot here in Italy EUR 30 for 1,

approximately $ 34

Waaaay too much thermal paste there mate.. you need half or quarter of a grain of rice per chip.

[marvykkio]

on pcb I arrive Tuesday put less thermal paste, the important thing is evenly cover the entire chip

[mavericklm]

you should edit first post as there is nothing understandable there!
put before.... and after...

[marvykkio]

What would I change?

The only problem with that MX-4 stuff is thats its very expensive. Its around $15 and its only good for only 1 miner.

ok , here r my stats....(before  and  after) :

PS:now the extenal temp is 32c but in thursday will gow at 39c so i must put the ant in the  ref/tor  and go to the beach

revelacaogr,  can you please test with or without cover at same room temp and same cooling?

thx!

Although $15 for thermal paste isnt cheap the price of the miner and room to overclock it slightly more can help offset some of the costs

i tested yesterday but i dont have a snap. I   can tell u for sure that:  without cover at same room temp and same cooling is 4-5c more
