First off find out what your ambient temperature is in the room you are mining in.

2nd run the miners and keep checking the temps while running and mining.

Temp 1 seems a little high temp 2 seems normal.

Maybe to change the direction of the unit try sitting it in different positions in where you are mining as sometimes better air flow will provide better temps. If your top temp is high and is one sided then sit it differently if the temps change and temp 2 goes hotter than temp 1 then this is a matter of controlling air flow correctly and need to sit it better. If theirs no change you could install as a option 2nd fan to the unit for push pull config and if that don't work then look to changing thermal paste on it.

Well if your not prepared to actually get down to inspecting it and changing then nothing much anyone can do . At least try some of the other options. Begging you wont get anywhere if you want cheaper wait for price to come down. If wanted to buy 2nd hand then why not go ebay or local places or even on here to buy equipment. Most machines will have some dust in it due to burn in test for a few hours to make sure units working before shipping.

If your units faulty I would give them a full brake down of what is going on what's happened and for a solution to be provided. Simplest solution  if you know how to is tear down the unit bit by bit and replace the compound could simply get dried up on sending out or just bad batch. When I got my Avalon from Avalon this was caked in it like icing on it cleaned up and worked fine. 1x S1 antminer had temps like yours took apart found that the paste was not evenly distributed across the board. Meaning this could of been due to production line running low on compound or it had ran out they inspected sent out and not noticed it. Something like this is a simple fix. And again could also be airflow too. Changed my units around 8 times in my room before finding optimal temps for all units on. So if you not prepared to do anything even tho you should not have to but sometimes have to then good luck in resolving your problem.

notlist3d, I don't blame bitmain for my corrupt government. I only wanted something that would cost them nothing, instead they did the opposite. I now only buy used hardware from the forum. Here's my current thread: https://bt.irlbtc.com/view/1063753.0

Crazyearner, first, I didn't beg anything. I misexpressed myself where I meant I asked many times, even offering to pay. Second, I didn't ask for a lower price, but a lower declared price on invoice. Third, this unit is brand new. If you buy a brand new car you expect it to leave the store working, not having to change the tires or something else.
I managed to decrease the difference to 8c instead of 14c myself. I will eventually check for further and more advanced options as I get more experience.

We did 

Dogie, that quote has nothing to do with bitmain. I already was aware they wouldn't help me at the time and even had paid them already. I was looking for other people or companies to sell me with lowered invoice. I wasn't asking whether bitmain lowered or not.

crazyearner, thanks for the video. I will definitely try further options on improving my mining performance. I have a few ideas in mind such as tunneling air conditioner straight into fan and having something vac the hot air out. Has anyone ever done such thing before?
I will also have the chips checked for thermal paste by this week, better take it slowly than screw up. Has anyone ever thought or already removed the side edges? The ones who have printed BITMAIN and ANTMINER. I think more air should flow if that is done. I remember we used to do that on computers before 1999.

This is what I currently have: http://prntscr.com/76tnu3
21c temperature outside according to google + air conditioner + 1 ceiling fan. Estimate 17c in room.
What do you guys think?

One of them is hotter than the other. Not an abysmal difference, but definitely noticeable if you touch the metal part that protects the chips. Judging from the time I can bear touching each I would guess it in fact is a 8-9c difference, which was what my panel was indicating at the time.
Like I said, I will have to check thermal paste eventually.

Don't know if this makes any difference, but take a look at my alluminum parts. Seems different from everyone's else. The blades are touching.

I also have 2 chips on each board without its metal parts, like all others. Don't know if this is normal.

Let me know what you think.

So you think they put s3 material on my s5? If they did that, some people still bash me for expecting minimum decent customer treatment... No wonder companies are like that if customers like it.

Here is the requested picture. You can see the gold thing. Each board has 28 chips protected with metal stuff and 2 unprotected.

Let me know if this is normal. I don't wanna say unfair or untrue about them or anyone else.

Remember I am in southern hemisphere so it's almost winter. I am on an air conditioned room with 1 ceiling fan at the time of last picture of my panel. It was night time.

I am absolutely sure that mining is not for you.

Your S5 is nothing wrong . Only a little bit wrong  showing  temperature sensor.  My one S5  sensor  showe  zero, But the miner himself worked properly.



This is normal.
I purchased 35x S5, none of them has these small radiators.



Half of my S5 had the flat ones heatsinks  and   Half of my S3 had the flat ones heatsinks.
S3/S3+ and S5 radiators is exactly the same.  Even the same size and the same weight.




Compare the things that are comparable in price.
If you buy  a new car  for 500 USD , I doubt that  there are  tires, probably the only wooden wheels.

Seeing them small tiny heat shields on units does look different compared to other batches maybe a new way in reducing weight and better heat spread but I would be looking into iver re doing the paste or try setting the units up and position them differently to see if makes difference in temperatures or to add a 2nd fan to the unit.
