MacBook Pro Retina's 15-Inch Model's Fan Speed Issue: Are SanDisk SSDs To Blame?

Apple's 15-inch Retina MacBook Pro has encountered some rough weather with the device's fan speed and disgruntled owners are bombarding the Apple support forum to vent their annoyance. Several MacBook Pro users have complained of issues with the device's fan speed, which is apparently owing to the SanDisk sold state drive (SSD).

iFans are experiencing unexplained bursts of system cooling fans shifting to fast speed. This issue is being blamed on the SanDisk SSD, which Apple recently replaced. Per reports, extremely loud fan noises are emanating from the Retina MacBook Pro even under light CPU load.

The issue came to light when a user posted a complaint on Apple's support thread. Within a short passage of time the forum grew to nearly 27 pages of complaints from frustrated users. However, Apple is yet to officially acknowledge or comment on the issue.

According to user "jamezmbp," who was the first to point out the problem, following the standard troubleshooting steps, which includes running the Apple Hardware Test utility, it did not resolve the issue or provide any insight into the problem.

"I bought a MacBook Pro Retina just under a month ago, and have been experiencing some issues with the fan speeds. I can be just browsing the web or checking emails or playing music through iTunes, and the fans will spin up to full speed for a minute or so, and then return to normal. I have reset the SMC, the PRAM and repaired the Disk and Disk Permissions, with no luck, I've also tried a full format and reinstall with no luck either," writes jamezmbp on Apple's support forum.

Moreover, a YouTube user "Oyinko" points that the early 2013 Retina MacBook Pro model's fan notches up the laptop's speed to a potentially harmful level, regardless of the unit's temperatute. Oyinko, as well as several other forum users, are of the opinion that the issue is related to SanDisk SSDs. However, some users reported the same issue with the Samsung-equipped SSD units of the Retina MacBook Pro as well.

"MacNN spoke with an independent testing lab who tried to reproduce the issue with eight previous-model Retina MacBook Pro laptops, five with the Sandisk SSD, and three with the Samsung SSD. Seven of the refreshed models were also tested. None of the 15 laptops examined were able to reproduce the issue, given the steps that were provided on the support forums to test machines," reports Electronista.

Speculations are rife that Apple will refresh both the MacBook Pro and MacBook Air lines in Q2 2013, possibly by June. The Cupertino company is expected to introduce internal enhancements and upgrades, but will likely retain the existing design.

It is not yet known when and if Apple will address the fan issue.
