Reports suggest Skylake CPUs are more easily damaged by overtightened heatsinks

Contact between the CPU and its respective heatsink/fan combination is one of the most important parts of keeping it cool. That’s why there’s heatpaste, and screws to tighten it down, but there is often a danger of tightening too much and doing damage. That’s apparently a little more common with the new Skylake generation of hardware, as reports have surfaced of a number of chips bending when attached to some cooler set ups, which can damage the motherboard socket pins below it.

This isn’t just a case of system builders and end users getting a bit overzealous with their CPU screws – though that won’t help – but because the structure of Skylake chips is a little different from previous generations. According to tests conducted by, it was discovered that Skylake CPUS have a thinner substrate.

Although more testing will certainly be required, it does suggest that users should be careful when applying coolers, and perhaps during the transport of their systems.

Individual manufactures have spoken out about the alleged issues. While Arctic Cooling has suggested that system builders using its coolers ship them without the heatsinks attached, it confirmed that none of its coolers have direct problems with mounting.

In contrast, Scythe has promised to revamp the mounting method for its coolers. While it did say that “in general,” its coolers were perfectly compatible with Skylake, it did admit that strong shocks during shipping while the cooler was fitted could be problematic.

Intel itself is said to be investigating the issue, but did not comment specifically on the statements made by Artic Cooling and Scythe. Instead the company, in a statement made to Tom’s Hardware, says there could be “several variables at play” in causing the issue, so it may not have to do with the chip at all. Intel did confirm that the substrate layer is thinner this generation, but is rated to to handle the same amount of force (5o pounds), so that shouldn’t be a problem.

If the problem is largely related to shipping it wouldn’t be a surprise to us. We receive desktops for review regularly, and damage is not uncommon. PCI slots weighed down by heavy cards seem another trouble area. We’ve received several systems with a slot that did not work. Most manufacturers now use inflatable foam packaging inside rigs to provide support in shipping.

Although somewhat unsubstantiated for now, we would recommend all users exercise extra care when fitting coolers to, and transporting systems using, Skylake hardware.

Intel’s CPUs just got way more confusing
Intel Core i5-14600K processor inside its socket.

Intel announced a slew of new processors during CES 2024, including mobile and desktop CPUs and the new Intel Core Series 1 made for thin-and-light laptops. Some are destined to make the list of the best processors, but Intel's naming conventions are only getting more confusing, with machines sporting both its old naming convention and the new Core Ultra rebrand in 2024.

Starting with the Intel Core HX series, Intel is introducing five new CPUs made for gamers and creators, starting with the high-end Intel Core i9-14900HX, followed by the Core i7-14700HX, the Core i7-14650HX, the Core i5-14500HX, and lastly, the Core i5-14450HX. The top chip in the lineup sports a whopping 24 cores and 32 threads.

Intel’s Core Ultra CPUs are more Apple, less AMD
Intel announcing the Meteor Lake release date on Intel Innovation.

Intel’s new 14th-gen Meteor Lake CPUs are finally here. The company officially announced its latest generation client system on a chip (SoC) lineup, which is claimed to deliver "game-changing performance" and power efficiency for the PC industry. Intel says it's the "largest client SoC architectural shift in 40 years," and it seems specifically targeted at Apple's wildly popular M-series processors.

The new Meteor Lake series introduces a major architectural shift as it is the first to be built on Intel 4 process technology. It makes use of the 7nm process and is designed using extreme ultraviolet (EUV) lithography to improve yield and area scaling to increase power efficiency.

Get ready to pay more for Intel’s next-gen CPUs
Intel Core i9-13900K held between fingertips.

Intel’s next-gen desktop CPUs are just around the corner, which means that we can expect even more leaks to make rounds on the internet. The latest one gives us an indication of what kind of pricing we can expect from the upcoming Raptor Lake Refresh.

As per a tweet shared by @momomo_us, Intel’s 14th-gen CPUs will be priced higher than the current crop of 13th-gen desktop processors. Notably, all the prices shared (in what seems to be a screenshot from a retail store webpage) are for the K-variants, which usually entice enthusiast and gaming consumers. The top-tier Core i9-14900K is set for a price increase of $95 compared to the 13900K, which was already an expensive chip at $600 during launch. The Core i7-14700K could carry a price of $485, while the most affordable overclockable desktop chip, the Core i5-14600KF, will be available for $345.
