৪–৮ হাজার বাজেটে Best CPU Cooler | Cooler Buying Guide 2026

Cooler-Buying Guide Summary

The presenter discusses CPU coolers priced roughly ৳4,000–৳8,000. Prices and availability may change. These are personal, mostly specification-based recommendations—not a full set of hands-on reviews. Many newer or less-established models have not been tested by the channel, so their real-world performance and reliability are uncertain.

Models discussed

Cooler Price / warranty Main points and cautions Arctic Freezer 36 A-RGB ৳4,150 / 6 years The presenter’s pick for the best overall single-tower option, particularly for its brand reputation and support. A dual-tower model may offer more cooling headroom; exact temperature performance was not established. First Player Cryo CY12D Black ৳4,250 / 5 years A dual-tower cooler for only ৳100 more than the Arctic. Suggested for buyers who want additional potential cooling capacity. A black version and RGB variants are mentioned. Performance is judged from specifications, not testing. DeepCool N600 (name may be unclear in the subtitles) ৳4,500 / 3 years Described as sleek and premium-looking, with a transparent section on the fan motor that reveals internal parts. Its heatsink is thinner than some other models, so the presenter advises considering CPU heat output before choosing it. DeepCool AG620 ৳4,700 / 1 year A dual-tower cooler with “decent” specifications. The presenter includes it as a competitive option, while noting that buyers may prefer other brands or models. DeepCool AK400 Digital ৳4,700 / warranty not stated A single-tower design with digital styling. The presenter does not recommend it at this price, since dual-tower alternatives are available for similar money. Consider it mainly if you like its appearance. Aperture UPTC 8C ARGB (brand/model transcription uncertain) ৳4,700 / 2 years A dual tower with eight heat pipes, which may help heat dissipation. Fan specifications are described as roughly mid-range. Expected to outperform many single-tower options in its price bracket, but this is unverified. OCYPUS Delta A62 BK About ৳5,000 / 2 years A promising-looking dual-tower option with aggressive specifications and fluid-dynamic fan bearings. The presenter likes its clean appearance and apparent value, but stresses that its real-world performance and reliability are unknown. Jgmak AK6 Dual Digital (name may be uncertain) ৳5,300 / 1 year A digital dual-tower cooler. Quoted fan figures are 78 CFM airflow and 2.24 mm H₂O pressure—slightly better on paper than the AG620 and the eight-heat-pipe cooler mentioned earlier. The presenter dislikes its appearance, a subjective concern. Thermaltake 140 V3 About ৳5,300 / 3 years Potentially a good value if still available. The presenter recalls it performing well in an earlier comparison, including under a demanding CPU load, and says it previously won a value-for-money award. It has two differently sized fans (120 mm and 140 mm) and four 8 mm heat pipes. It has a non-RGB appearance; current availability and performance are uncertain. Thermalright Royal Knight 120 Digital ৳5,900 / 3 years A dual tower designed to accommodate taller RAM: its front fan is reduced from 25 mm to about 15 mm. The slimmer fan may reduce airflow and performance, though its blade design may help compensate. Best suited to buyers specifically concerned about RAM clearance. OCYPUS Delta L24 BK AIO ৳5,350 / 3 years A 240 mm liquid cooler with quoted fan figures of 73 CFM and 4.3 mm H₂O. Considered unusually inexpensive for a 240 mm AIO and promising on paper. It uses HDB/hydraulic-style bearings rather than fluid-dynamic bearings. It is untested, so performance and reliability remain unknown. Thermaltake Toughair 17 ৳5,650 / 1 year Recommended for buyers prioritizing air-cooling performance over RGB. The presenter recalls it as a strong performer in a prior comparison and particularly praises its fan quality. It is a dual-tower air cooler with a 140 mm fan. Air coolers are presented as a safer, more reliable choice than inexpensive AIOs because they do not carry liquid-leak risk. Afera 240K AGB (brand/model transcription uncertain) ৳6,000 / 5 years An established budget AIO with a notably long warranty. The presenter says its performance was acceptable for its price, though below that of more expensive coolers, and describes its appearance as simple and minimal. Suggested for buyers who prefer a more established option over a new, untested brand. OCYPUS Delta A62D H, white ৳6,200 / 3 years A digital cooler with a small dot-matrix-style temperature display, not a full LCD. The presenter notes improved fan specifications over the cheaper model, but it has not been tested. The display’s appeal is subjective. Thermalright Royal Petar 130 Ultra ৳6,400 / 3 years Presented as a high-performance air cooler. Its fan specifications look promising; the presenter estimates its performance may be around that of a good 240 mm AIO, but not a 360 mm model. DeepCool LT 520 ৳6,500 / 5 years, to be confirmed Quoted specifications are 85.85 CFM and 3.27 mm H₂O. The presenter warns of reported pump-failure issues in the LT 520/720 series, citing roughly two pump problems over two years in their experience. Warranty and pricing may differ between official and unofficial stock, so confirm coverage with the seller or distributor before buying. It may be end-of-line stock. OCYPUS Delta L36H AGB ৳6,600 / 3 years A 360 mm AIO, praised as an unusually affordable option. Its fan specifications are said to resemble those of the L24. Suggested for buyers with limited budgets who specifically want a 360 mm liquid cooler, but actual performance and reliability are unverified. DeepCool LS 520 S Zero Dark ৳7,200 / 3 years An honorable mention, said to perform similarly to the LT 520. It is an alternative if the LT 520’s appearance is not to your taste, though it costs more. Zimatek LK 240 Pro AIO About ৳7,400 / 3 years The channel has a separate review. Its standout feature is a display that can show several kinds of system information, rather than temperature alone, but it is not customizable. The main drawback is that the fan is reported to be noisy. The presenter recommends it mainly for buyers who particularly want a display. OCYPUS Lata L24 BK ৳7,900 / 5 years A 240 mm AIO with quoted fan figures of 77 CFM and 4.65 mm H₂O. It has a dot-matrix-style temperature readout, fluid-dynamic fan bearings, and a pump described as using ceramic bearings and a three-phase, six-slot motor. These specifications appear unusually generous for the price, so the presenter advises sensible caution rather than blind trust. It has not been tested. Belltop Tidal 240 / Tidal 360 ৳6,200 / ৳6,700; warranty not stated An honorable mention from a Bangladeshi brand. The presenter could not obtain specifications or enough information about the display or performance. Since the 360 mm version costs only ৳500 more, it is the preferred size if choosing between the two, though its quality is unknown.

Main takeaways and comparisons

• Single tower vs. dual tower: The Arctic Freezer 36 is the presenter’s preferred single tower, but dual-tower models such as the First Player Cryo CY12D offer more potential cooling headroom for slightly more money.
• Air cooling vs. liquid cooling: Air coolers are presented as the more reliable, lower-risk choice, especially at budget prices. AIOs may offer appealing sizes, displays, and specifications, but leakage and pump reliability are concerns.
• New or untested brands: Several OCYPUS and other budget models look strong on paper, but specifications do not guarantee real-world performance.
• Warranty matters: Check the seller’s coverage, particularly for DeepCool products, where official and unofficial stock may have different warranty terms.
• Performance evidence: The video gives no numerical ratings or benchmark scores. Comparisons are largely based on the presenter’s past experience or on stated specifications.

Verdict

For a conservative air-cooler choice, the presenter favors the Arctic Freezer 36 A-RGB as a single tower and highlights the First Player Cryo CY12D as an inexpensive dual-tower alternative. The Thermaltake Toughair 17 is recommended for buyers focused on air-cooling performance.

Budget AIOs—especially the OCYPUS models—look attractive in terms of specifications and price, but should be treated as promising, unverified options, not guaranteed performers. Verify availability, price, and warranty before purchasing.
