Intel discontinued production RS1 Laminar standard cooler, which was previously the cheapest model among the company’s three standard coolers.
Introduced in 2021 with 12th generation Alder Lake processors.The RS1 has an all-aluminum construction with a plastic casing that measures just 47mm in height and weighs around 260g. Essentially, this is an updated version of the old standard Intel cooler with a more optimally designed heatsink and a larger five-blade fan designed to cool 65-watt chips.
Intel also has two other standard coolers: RH1 and RM1. The RM1 is almost identical to the RS1, except it has a copper plate at the bottom for better heat transfer, as well as an LED strip surrounding the fan. Like the now-discontinued RS1, the RM1 is also rated at 65W. The RH1, meanwhile, has a completely different design: it’s taller, uses more copper, and has a higher quality metal casing.
The RS1 only ever shipped with two dual-core processors: Pentium Gold G7400 and Celeron G6900. While Intel’s weakest stock cooler isn’t particularly reliable, it cools both the G7400 and G6900 without issue, since both have a TDP of just 46W.
This is probably one of the main reasons why it was discontinued. It’s hard to justify creating a standard cooler for just two processors, let alone dual-core Pentiums and Celerons, which haven’t been particularly popular lately.
Intel says the RS1 won’t have a direct successor, but will simply be replaced by the RM1. Simplifying standard coolers could also be another motivation for Intel to move away from an all-aluminum cooler, since the RS1 and RM1 are already nearly identical. RM1 is already used for the vast majority of locked Intel processors, starting with the 12th, 13th and 14th generation Core i3 and Core i7.
RM1 is also used for Intel Processor 300, renamed Pentium G7400.. The 300 came out about a year ago, and the fact that it used the RM1 was perhaps a sign that the RS1 wouldn’t be around much longer.
