Dispelling Myths: The Unjust Criticism of Soldered Heatsinks in Bitcoin Mining

Table of Contents

In the evolving and complex landscape of Bitcoin mining, the Antminer 17 Series has often been misunderstood and prematurely dismissed. The narrative that prevailed in the industry painted the Antminer 17 Series as a flawed model, casting a shadow over its real potential. This precipitous judgement often stemmed from a prevalent lack of technical knowledge and understanding in the crypto mining sphere.

The art and science of Bitcoin mining is not simply about harnessing computational power. It necessitates a deep comprehension of the underlying hardware, its strengths, weaknesses, and idiosyncrasies. Unfortunately, many brokers, resellers, and repair centers that operate in the sector today lack these critical competencies, leading to hastily drawn conclusions and misguided decisions.

Navigating this nascent industry requires patience and a penchant for meticulousness, qualities that many in the fast-paced world of crypto often overlook. It’s not about who can acquire the latest gear the fastest, but who can unlock the true potential of the tools at hand.

Our Expertise and Dedication

When it comes to ASIC models, particularly those of Bitmain, few can rival the dedication and prowess of D-Central. Our expertise is not just based on theoretical knowledge but on hands-on experience and thorough investigation of each model’s functionality and potential issues.

Many in the mining world were quick to dismiss the Antminer 17 Series, and later the Antminer S19j Pro+, citing the soldered heatsinks as a major design flaw. This prevailing belief held that soldered heatsinks were the root cause of performance issues in the 17 series. Consequently, many assumed that the Antminer S19j Pro+ would suffer the same fate. However, this is a classic case of misguided correlation leading to false conclusions.

Through our rigorous examinations, we discovered that the true issue with the 17 Series was not the soldered heatsinks but the inadequate quantity of soldering on the chips, a clear indication of poor manufacturing. When handled with care and the correct technical know-how, soldered heatsinks are not a liability but a reliable element of design.

We’ve put this theory to the test by successfully resoldering and fixing numerous Antminer 17 Series machines. The results? Uninterrupted, high-performance hashing for hundreds of days. It’s a stark contrast to the prevailing narrative, and one that challenges even large-scale mining operations that lack the specific expertise required to identify and correct this issue.

At D-Central, we’ve not only demonstrated that the Antminer S19j Pro+ has been unjustly dismissed, but we’ve also brought to light the importance of a deeper, more technical understanding of ASIC models. Our approach challenges superficial assessments and highlights the untapped potential in models often overlooked by the wider industry. In the end, our clients and the broader Bitcoin mining communities are the beneficiaries of this unconventional wisdom.

The Real Issues with the Antminer 17 Series

The Antminer 17 Series, although maligned by some, is an example of how surface-level assessments can obscure the true potential of an ASIC model. The common misconception is that the soldered heatsinks are to blame for the performance issues seen in this series. In truth, the actual culprits were chip delamination caused by poor manufacturing and insufficient soldering.

Chip delamination in the 17 series was a result of hasty and subpar production standards, leading to an inadequate quantity of soldering on the chips. This seemingly small oversight had a significant impact on the performance and reliability of the units. But rather than recognizing the root cause, many hastily pointed to the soldered heatsinks as the issue.

At D-Central, we strive to challenge such misconceptions and promote a deeper understanding of the intricacies involved in Bitcoin mining. Our hands-on experience and rigorous testing have shown that with proper intervention and technical acumen, the Antminer 17 Series units can be transformed into highly effective and reliable mining hardware.

These units, once properly fixed, have been proven to hash at high-performance rates for hundreds of uninterrupted days. This not only refutes the prevailing narrative around the 17 Series but also highlights the importance of detailed knowledge and intervention in achieving optimal results from mining hardware.

Simply put, it’s not the soldered heatsinks that make or break the performance, but rather the quality of manufacturing and the amount of technical know-how employed in maintaining and fixing these units.

The True Outperformer: Antminer S19j Pro+

Amidst misconceptions and quick judgments, the Antminer S19j Pro+ stands as a beacon of the impact quality manufacturing and precise design can have on a unit’s performance. This unit shares the soldered heatsinks feature with the Antminer 17 Series but doesn’t exhibit the same problems, courtesy of a superior manufacturing process.

The Antminer S19j Pro+ is a demonstration of how soldered heatsinks, when done right, can enhance the performance and reliability of mining hardware. Thanks to precise and quality-centric manufacturing, the correct amount of soldering is attached to the chips, bypassing the issues that marred the 17 Series.

Crypto miners who have had hands-on experience with this model have shared their positive experiences on social media. Altair Technology® stated on Twitter, “Was a bit skeptical of these when they came out, but they’ve grown on me. Hard to beat them on $/Th basis.” Another seasoned miner, Bob Burnett, who has been running a substantial number of Antminer S19j Pro+ units for several months, vouched for their performance, “We’ve been running a fairly large number of them for several months. Performance and reliability have been solid thus far.”

In comparison to other models in the 19 Series like the Antminer AL, Antminer 90T, and Antminer S19 XP, which use the aluminum substrate hashboard, the Antminer S19j Pro+ shines in its performance and value for money, making it a choice that savvy miners won’t regret.

Comparison with Other Models

Choosing the right hardware is a critical factor in Bitcoin mining. Let’s delve deeper into how the Antminer 17 Series and the Antminer S19j Pro+ stack up against other models such as the Antminer AL, Antminer 90T, and Antminer S19 XP.

Model Performance Reliability Value for Money
Antminer 17 Series High (with proper resoldering) Moderate (issues due to poor manufacturing) Good (potential for high performance with proper maintenance)
Antminer S19j Pro+ Very High (superior manufacturing process) High (no significant issues reported) Excellent (high performance and reliability)
Antminer AL High (powerful but can be inconsistent) Low (reported to be unreliable) Moderate (performance can be high, but reliability issues affect value)
Antminer 90T High (solid performance) High (reliable with proper maintenance) Good (reasonable value for the performance)
Antminer S19 XP High (latest technology, powerful) Low (reported to be unreliable) Moderate (high performance, but reliability issues affect value)

The Antminer 17 Series, when properly resoldered and maintained, can deliver high performance, although its reliability has been compromised by manufacturing issues. The Antminer S19j Pro+, on the other hand, stands out for its very high performance and reliability, thanks to a superior manufacturing process, making it an excellent value for money.

The Antminer AL and Antminer S19 XP, while powerful, have been reported to be unreliable, which affects their overall value for money. The Antminer 90T offers solid performance and high reliability, making it a good value for money.

In conclusion, while each model has its strengths and weaknesses, the Antminer S19j Pro+ stands out as a particularly strong choice due to its superior performance, reliability, and excellent value for money.


The world of Bitcoin mining is often clouded by misconceptions and rapid judgments. A notable example has been the Antminer 17 Series and the newly introduced Antminer S19j Pro+, both of which have been wrongfully dismissed due to issues attributed to soldered heatsinks. However, our thorough analysis at D-Central revealed that the problem with the 17 Series was primarily poor manufacturing leading to chip delamination, a problem not inherent to the design or concept of soldered heatsinks themselves.
