After several weeks of user complaints, Microsoft has acknowledged heat issues in the Core i7 version of its Surface Pro 3 tablet.

In a statement sent to PCWorld, Microsoft avoided using the term “overheating,” but said users should expect the Core i7 model to run warmer than its less-powerful siblings.

“The i7 version of Surface Pro 3 is a first-of-its-kind tablet delivering i7 processing power in a thin and light package,” Microsoft said. “As such, the increased power calls for the fan to spin more regularly and at higher speeds—and for the unit to run slightly warmer.”

But what about users who've experienced a temperature warning icon on the screen? Microsoft said a software bug is actually triggering this warning by accident, and only on a “very small number” of Core i7 models.

“Our investigation reveals that the system is triggering this event sooner than it should for some people, only when the device restarts, and this does not occur when the device is booted and running,” Microsoft said. “We have an update that will address this that will be ready for our customers as soon as possible.”

It's possible that some of the heat issues—which users said would occur even during light computing tasks—are related to Windows updates that Microsoft applies in the background. As Neowin reported earlier this week, some users managed to cool the system down by killing Windows Installer Module and Windows Installer Module Worker in the Task Manager. One user told me that his Surface Pro 3's heat issues went away after the system installed its initial batch of updates.

Still, if you'd rather have a Surface Pro 3 that's cooler to the touch, and don't mind sacrificing some computing power, you may want to stick with the Core i5 model, which is considerably cheaper anyway.
