- Black Friday 2026 is a useful time to compare model variants and included accessories, not just product names.
The DeepCool AK400 is the best all-around pick for most single-tower builds, while the ID-COOLING SE-224-XTS Black is a straightforward value alternative. Both use four heatpipes and a 120 mm fan, making either a meaningful step up from many basic stock coolers. The best choice depends on case clearance, socket compatibility, noise priorities and the exact variant on offer.
For this Black Friday 2026 guide, I researched and compared specs, reviews and owner feedback across seven tower coolers. The selections include simple budget models, an all-black AK400, a digital-display version and a larger dual-tower option. My pick for most people is the DeepCool AK400: its common 155 mm height and uncomplicated design make it easy to compare with typical mid-tower cases. Confirm current compatibility and dimensions before checkout.
How We Picked

Which is better, the ID-COOLING SE-224-XTS or DeepCool AK400?
The DeepCool AK400 is the more balanced pick for most builds, while the ID-COOLING SE-224-XTS is a value-focused alternative with 4 heatpipes and a 154 mm height. Both use a single 120 mm fan, so the main choice comes down to case fit, finish, price at the time of purchase and the exact product version.
The AK400 stands 155 mm tall and has a well-established, simple layout. The SE-224-XTS is a millimeter shorter on its listed specification, which gives it a small fit advantage on paper. Neither difference alone determines CPU temperature: the processor, case airflow, fan curve and room temperature all matter. Skip it if the model listing does not clearly identify the variant or supported socket.
What should I check before buying a CPU air cooler?
A PC cooler purchase should start with socket compatibility, case clearance and RAM clearance, not the heatpipe count alone. Check the exact cooler’s listed support for the processor’s motherboard socket and confirm that the case supports the tower’s full height.
The DeepCool AK400 and Thermalright Peerless Assassin 120 SE are both listed at 155 mm tall, while the ID-COOLING SE-224-XTS Black is 154 mm. Those measurements do not confirm fit by themselves: side panels, motherboard layout and fan position affect clearance. A large dual tower also sits closer to memory modules, so compare the cooler drawing with the RAM height before ordering.
Is a dual-tower cooler better than the AK400?
The Thermalright Peerless Assassin 120 SE has more cooling hardware than the DeepCool AK400, with 6 heatpipes, two towers and two 120 mm fans. That design makes it a better match for higher CPU heat loads when the case and budget support a larger cooler.
The DeepCool AK400 remains the simpler choice for mainstream builds that do not need a dual-tower heatsink. A larger cooler also adds more parts to fit around the motherboard, including memory modules and nearby components. For a build that prioritizes easy dimensions and a single-tower layout, the AK400 is easier to assess. For workloads that sustain high CPU use, compare independent thermal results for the exact processor before making the final call.
Should I choose a black or digital AK400 variant?
The DeepCool AK400 ZERO DARK is the right AK400 variant for an all-black appearance, while the DeepCool AK400 DIGITAL is the option with an integrated display. Both retain a four-heatpipe, 155 mm tower format, so their main distinction is added presentation rather than a different cooler size.
Choose the standard DeepCool AK400 when a plain look meets the build’s needs. The ZERO DARK finish coordinates with dark motherboards and cases, while the DIGITAL model puts system information on the cooler. Check the exact listing for display requirements and included accessories. Model names can be close, so verify the full product name before purchase instead of relying on a thumbnail or short listing title.
How should I compare these coolers during Black Friday 2026?
A useful Black Friday 2026 comparison starts with the exact model, included hardware and fit details, then considers the final retailer offer. The ID-COOLING SE-224-XTS Black, DeepCool AK400 and DeepCool AK400 ZERO DARK are single-tower options; the Thermalright Peerless Assassin 120 SE is a larger dual-tower alternative.
Compare the same variant across retailers and confirm whether a listing includes the required mounting parts and fan. Read recent owner feedback for notes on installation and noise, and check the return policy in case a cooler does not clear the case or memory. A low headline offer is not useful when the listing is the wrong version or the cooler does not match the socket.
Buying Guide
Match cooler height to your case
The DeepCool AK400 measures 155 mm tall, and the ID-COOLING SE-224-XTS Black measures 154 mm. Compare the exact number with your case’s CPU cooler clearance, leaving room for the side panel and any fan adjustments.
Confirm motherboard socket support
Check the product listing and manufacturer support page for your exact socket before ordering. Cooler revisions and bundles vary, so confirm that the included mounting hardware supports your processor and motherboard.
Account for memory and motherboard clearance
The Thermalright Peerless Assassin 120 SE’s dual-tower layout needs more attention around RAM than a simple single tower. Check the manufacturer’s clearance guidance and your memory height before finalizing a build.
Choose the right cooling class
Four-heatpipe single towers suit many everyday and gaming configurations. Higher sustained CPU loads favor a larger design such as the Thermalright Peerless Assassin 120 SE, provided the case has room and reviews support the intended processor.
Compare exact variants and included parts
The DeepCool AK400, AK400 ZERO DARK and AK400 DIGITAL are distinct versions. Verify finish, display features, mounting hardware and fan details on the listing, then compare the same version across retailers for Black Friday 2026.
