Furzumz,
Although you're correct that
darklord.dl62's i3-4170 is too hot at 90°C, the "max allowed temperature" of 72°C that you posted above is not correct. Don't feel singled out; you're not the first person to misinterpret Intel's thermal specifications, and you certainly won't be the last, because Intel's definitions and terminology are tricky. For the benefit of other forum members and our visiting readers, we'll clear up the confusion.
The thermal specification for the
i3-4170 that's shown on Intel's
Product Specifications website is "Tcase", which has been misleading users since 2006.
Tcase is not Core temperature.
Users can't measure Tcase; it's a
factory only thermal measurement performed on
engineering samples using a
thermocouple sensor embedded on the external surface of the Integrated Heat Spreader (IHS) where the cooler is seated.
Retail processors do not have this sensor, so you can't measure IHS temperature (Tcase), nor are there any monitoring utilities to display it.
Core temperatures are instead measured deep within the Cores at the transistor "Junctions" which are the heat sources where temperatures are highest. This means the temperature is significantly lower on the IHS underneath the cooler.
For 4th generation desktop processors, Intel's thermal specification for maximum Core temperature, which is also called Tj Max (
Temperature
Junction
Maximum) or "Throttle" temperature is
100°C.
Intel's Product Specifications website, which is a quick reference, instead uses the term "Tjunction". Intel used Tcase for 6th generation and earlier processors, then switched to Tjunction for 7th generation and later. However, both Tcase
and Tjunction thermal specifications are shown on Intel's
Datasheets (see pages 67 & 73), which are detailed technical documents, that unlike the website, use proper terminology.
The processor's generation determines which of the two thermal specifications is shown on the Product Specifications website. Intel's intended purpose for providing Tcase specifications was primarily for developers of aftermarket cooling solutions.
For the record:
Tcase
Max is a specification
value for CPU coolers
Tcase is
IHS temperature
Tj
Max is a specification
limit for Throttle protection
Tjunction is
Core temperature

darklord.dl62,
Intel's stock coolers are notorious for the push-pins to stretch over time, or pop loose from the motherboard, so dust may not be the only problem; check for a loose push-pin. Additionally, be aware that although the GAMMAXX 400 is a decent cooler, it also uses push-pins. You might want to instead select another inexpensive cooler that has proper fastening hardware with a backplate.
