[QUOTE="ValterV, post: 1916610, member: 379916"] I second that. When I bought my 2009 24" iMac (still going strong :-) ), I noticed that some components got really hot (the Northbridge chip could reach almost 70° C!). Since my iMac has several fans, I deduced Apple decided to make them go slow to avoid excessive noise. You're confirming I was right. After all, if your Mac dies from overheating after 3 or 4 years, Apple is more than happy to sell you a new one... >:-( My solution was to install [URL='https://www.eidac.de/']smcFanControl[/URL] (donationware), and to create different fan speed profiles depending on ambient temperatures and usage. This way it's ME who controls how hot my Mac can become. TL;DR: Do not trust Apple on temperatures. Check them with some tools and, if hot, adopt a fan speed app to set them right. NB: Max recommended temps are different depending on the part (e.g. HDD, CPU, GPU...). [/QUOTE]
