ARCTIC Identifies Bad Batch of MX-5 TIM in the Market, Offers Free Replacements
For ARCTIC, it has always been a top priority to supply customers only with products of the best quality and durability. Should there ever be any doubts about products we've delivered, we stand by our responsibility to our customers.
Current findings from our permanent quality assurance tests show that certain batches of our MX-5 thermal compound contain anomalies in consistency and shelf life. The affected products show an increased separation of oil within the paste, resulting in premature hardening. This can lead to adverse effects and application difficulties.Affected batches have already been identified and recalled from circulation so that no further affected product can enter the market. We regret that this quality defect could not be detected before delivery to distributors and customers, despite constant quality controls and diligent care during production.
Affected MX-5 thermal compounds can of course be returned without exception, and we will offer a replacement product. For this purpose, we ask you to contact us and provide proof of purchase via the form support.arctic.de/en/menu/support.

I've also contacted them today. I'm curious to see if they will going to replace it with an MX-5 or MX-4.
I'm using the MX-5 on an i9-12900k and I've observed in 2 months of use my temps got higher with ~5C . I thought that it's the motherboard manufacturer as I've upgraded my BIOS 7 x times in the last month - new platform (Z690) and a lot of new BIOS updates has been released.
Next week I'm building my 2nd rig with an i7-12700k and hopefully I will get the new (good) paste till then.
I'm a fan of their products and I own 2 x Arctic LF II - 1 x 420mm and 1 x 360mm
Its a guaranteed way to get a product with no risk of quality control issues, at least... but not if you end up paying 5x the cost of the MX4 alone
MX-5 also seems to be discontinued by arctic. Its not on available for purchase from their website and it's listed as an end of life product, which probably explains them giving out mx4 as a replacement rather than mx5.
