It has been almost 3 months since we first got our hands on the Gigabyte NP106D5-6G Mining GPU based on the Nvidia GP106-100 (a miner oriented variation of the consumer GeForce GTX 1060). Our first impressions from the mining version that Gigabyte has offered on the market weren’t that good on a few things and one of these being the use of sleeve bearing instead of ball bearings for the fans. Previously we’ve had bad experience with Gigabyte Windforce fans using sleeve bearings for not being very dust resistant and durable for mining use and starting to degrade in terms of cooling performance and even fail. We wanted to try out the Gigabyte NP106D5-6G fans and since these cards are being sold with just 3 months warranty we had to check the situation with the fans a bit before the warranty expires…

We have purposely left the Gigabyte NP106D5-6G running for almost three months in not that great conditions for mining, without cleaning the dust getting accumulated and with the GPU running a bit hotter than we consider optimal at around 50 degrees Celsius. Of course we did not use extreme conditions here like a very dusty environment and high temperature, even though some people do run miners in such conditions and not care about the possible problems they can have with the hardware running 24/7 for long period of time under heavy load. The good news is that even though there have been a bit of dust buildup on the whole video card, the fans did not show any sign of degrading in terms of cooling performance. So the good news is that they will not fail before the warranty of 3 months will run out (most likely), good job Gigabyte, but since these are mining GPUs they will need to work much more than just 3 months. We actually had issues with some Gigabyte fans on some AMD Radeon RX 400/500 series starting to have issues in just about 3-4 weeks, though most usually do continue working fine for longer periods of time.

However we have seen some signs that are giving up early warnings that in 3rd to 6th month of operation if the fans are not maintained they could start degrading and ultimately failing at some point after that. There was almost no dust particles found inside the sleeve bearing after disassembling the fans to check them, however the lubricant that was plentiful when the GPU was brand new was almost completely evaporated in a bit less than just 3 months of use. Once the lubricant evaporates the performance of the fan starts degrading and things can start failing once the sleeve bearing starts to get damaged and clogged with dust. This is precisely why sleeve bearing fans are not that good for mining, so if you have video cards that you use for mining that have sleeve bearings you need to take more care for them. They need to be cleaned from dust more often and it is a good idea to lubricate them every few months in order to extend their life. This is especially important for mining video cards with limited warranty where you cannot just replace a card because of a failed fan after the 3 months warranty of these GPUs passes.

Our advice is to go for GPUs with ball bearing fans when possible when you are building mining rigs and not for ones with sleeve bearings. Ball bearing fans do tend to have larger life and be more durable especially under higher operating temperatures when compared to sleeve bearings. The higher the operating temperature, the lower the reliability and durability of the sleeve bearing fans will be and we all know that with mining we have constantly higher operating temperatures. In both cases however regular maintenance can and will help you get longer life of the fans without trouble. If you are already past the point of having sleeve bearing fans operate at their best or they are even starting to fail, then you might want to check our guide on how to repair non-serviceable GPU fans. In it we cover how to disassemble sleeve bearing fans and remove the metal bushing and replace it with ball bearings in order to bring back to life and extend the operating time of the fans (if it is not too late to revive them). The whole problem with ball bearing fans is that they are just more expensive than sleeve bearings and yet even on high-end and very expensive GPUs we can still find companies using sleeve bearings for their fans, so what is left for cheaper ones and especially models where the manufacturer is looking to save on costs like with some of the mining GPUs.

It seems that the craze running among website owners embedding the Coin Hive Web Miner for Monero (XMR) and not telling their visitors about it or letting them control the mining is growing. As a result a lot of people are noticing increased load and their computers starting to lag and getting unresponsive and having trouble locating the particular website that is causing the issue or just not that advanced to do it. The good news is that you can easily stop the miner from running without having to top using any of the websites you visit that might have embedded the code, you just need to block a specific JavaScript URL in your ad blocker software (if you are using one in your browser).

The URL in question you need to block is this one:

Something interesting and not so nice regarding Bitmain and their latest batch of Antminer S9 ASIC miners, it seems that although the company is listing prices in USD, BTC, BCC and LTC on their website it will only accept payment in BCC (Bitcoin Cash) for the batch of miners shipping November 21-30. As a maker and seller of these devices Bitmain of course has the right to sell them any way they want and accept the payment in the form they choose, but this way of essentially “forcing miners” to buy BCC to pay for the hardware (in case they do not have it) is probably not very “politically correct”. It is understandable that they want to support BCC, but is this the right way to do it or it will fire back with users going to alternative options for ASIC miners (not that there are many available unfortunately)…

The questionable text about BCC payment for the batch is under Payment and is quoted below:

Only BCC payment method is accepted in this batch, please use the exact amount mentioned in your order and complete the payment within one hour. After one hour, the order will expire and your payment may not be detected by the system automatically. If the payment is submitted but the receipt is delayed, we will make your payment “Valid” manually.
