Cooler Master and G.SKILL have teamed up to engineer a sleek-looking air-cooled DDR5 kit called MasterDimm AC. Air-cooled memory is making a comeback, something not commonly seen since DDR3 and G.SKILL had several products featuring it back then. This time around, with the help of Cooler Master, those seeking the faster speeds of DDR5 can keep their kits cool with the CU-DIMM kits capable of running up to 8400 MT/s with Intel XMP 3.0.
Per Press Release (via TechPowerUp):
“Extreme Speed, Sustained by Dedicated Active Cooling Featuring support for AMD EXPO memory overclock profiles up to DDR5-6000 CL26 and extreme-frequency DDR5 CU-DIMM up to DDR5-8400 with Intel XMP 3.0, the co-engineered solution combines G.SKILL’s elite overclocking memory technology with Cooler Master’s dedicated active thermal architecture to sustain peak DDR5 performance beyond conventional thermal limits.”

“Designed for next-generation AI computing, gaming, content creation, and professional applications, this new memory supports ultra-high capacities up to 64GBx2 while maintaining long-duration stability under intensive workloads”
– Cooler Master/G.SKILL
Key Product Features
- Next-Gen DDR5 Memory Platform: Super low latency up to 6000 MT/s CL26 (AMD EXPO), extreme-frequency CU-DIMM up to 8400 MT/s (Intel XMP 3.0)
- Advanced Active Cooling Technology: MasterDimm AC active cooling provides up to -15°C thermal improvement
- Quiet Thermal Design: A noise-optimized blower fan and specially designed air flow heat sink allow for greater cooling under 35dB volume
The new MasterDimm kits will be available in up to 128 GB capacities (2x 64 GB) and will be on display at Cooler Master’s Computex booth. They have been developed with acoustic noise in mind and have an “integrated cooling architecture is engineered to deliver efficient heat dissipation with a controlled noise profile, enabling high-frequency DDR5 operation while preserving a quieter and more refined PC experience.”
Pricing and availability have not yet been announced, but could be revealed soon at Computex, where Cooler Master’s theme this year is Thermal Authority.

I love the idea.
I have negative faith in the execution.
I expect that the cooling will be sub-par and offer little if any benefit, based on just how horrific most companies are at designing heatspreaders for their RAM. I expect the solution to be loud. And I expect the fans to be unreliable, making them louder over time and failing early. After they fail, I expect cooling to be worse than if a normal heatspreader were installed instead.
Oh, and I expect the price premium to be ridiculous.
I don't enjoy being a Debbie Downer, but there are a lot of hurdles for G.Skill and Cooler Master to overcome for this to even be an 'okay' product.
It seems like a fair bet that Cooler Master did the design work for the heatspreader. Hopefully on the show floor they'll show the cooling solution properly as of now it's just a guess as to the design.
It doesn't really take much to cool DRAM so if the fins on the left are real and there's a heatpipe attached to them it ought to do rather well. I run a kit of Team Group Xtreem (non-RGB) which have good heatspreaders, but adding 80mm fans blowing down on them reduced heavy load temps by around 10C so to me the extra air movement is the biggest part of this design. As long as the system these are installed in isn't minimum noise while having an open case design I doubt the fans will be heard. Longevity and replacability of the fans would be my biggest concern as without them I doubt the cooling will perform any better than a good heatspreader.
That's my primary concern. I expect the things to work until the fan starts to die. I don't expect replacements to be easy, really I don't expect them to be available at all, and I expect the noise while they're failing to be overwhelming.
I expect them to perform worse. The design is based on forced airflow through an enclosed space; without that airflow, it's more like an oven.
I'd happily be proven wrong if @Brent_Justice could do initial and long-term reviews of course.
Yo dawg, we heard you like that founder's edition blower, so we put it on your ram, so you can have tiny blowers to remind you of the big blower when they are blowing.
Largely pointless gimmick with more moving parts to break. Hoping to capitalize on fears of ram dying on you. Time stamped

Not really RAM dying, but guaranteeing cooling (for the life of the fan).
Wasn't it corsair that had actively cooled Dominator ram back in... DDR3 days? I seem to recall that. Never took off... just buy ram that works and properly cool your case. If you're running an SFF likely you don't have space for a cooler and if you're not then your airflow sucks if you need this.
