Base materialiThe surface that touches the CPU: the heatsink base or the AIO cold plate. Plating counts, so nickel-plated copper is not copper. Direct-touch heat pipes are the contact surface, so they count as copper unless plating is stated. The direct-contact heat pipes field records the design.

Nickel-plated copper1Maker product pagethermalright.com/product/peerless-assassin-120-seRead 16 October 2026Copper Base: C1100 Pure copper nickel plated.

Copper8Reviewaphnetworks.com/reviews/thermaltake-ux200-seRead 15 October 2026Page 2: the base is made of aluminium and copper. The four copper heatpipes touch the CPU. Direct-touch pipes count as the contact surface, so the base is stored as copper by the plan rule.

Compatibility

1 of 3 differ

CPU socketsiSockets the maker lists as supported in its spec table, compatibility list or guide, written as cpu_socket writes them, e.g. AM5 or LGA1851. List each socket on its own, so LGA115x becomes LGA1150, LGA1151, LGA1155 and LGA1156. When the maker names the sockets of such a family, list only the ones it names. A socket that needs a separately sold or requested mounting kit is left out. A new socket that the maker lists with no extra kit counts. LGA2011-v3 and 2011(V3) are written LGA2011-3. Threadripper sockets use AMD's names, so TR4 is written sTR4 and TR5 is written sTR5. sTRX4 and sWRX8 are sockets of their own.

AM5, AM4, LGA1851, LGA1700, LGA1200, LGA1156, LGA1155, LGA1151, LGA11501Maker product pagethermalright.com/product/peerless-assassin-120-seRead 16 October 2026Intel 115X/1200/1700/1851 and AMD AM4/AM5. 115X is written as LGA1150, LGA1151, LGA1155 and LGA1156. The older installation guide covers AM4, 115X/1200 and 1700 only. The page names AM5 and LGA1851.

AM5, AM4, AM3+, AM3, AM2+, AM2, FM2, FM1, LGA1851, LGA1700, LGA1200, LGA1156, LGA1155, LGA1151, LGA11501Maker product pagethermaltake.com/products/ux200-se-argb-lighting-cpu-coolerRead 15 October 2026Compatibility: Intel LGA 1851/1700/1200/1156/1155/1151/1150 and AMD AM5/AM4/FM2/FM1/AM3+/AM3/AM2+/AM2. The page says the all-in-one back-plate fits all the latest Intel and AMD sockets, so no extra kit is needed. The 2022 manual and older shop copies list sockets only up to LGA1700 and AM4.4Owner's manualfile.thermaltake.com/file/qig/UX200SE_manual.pdfRead 15 October 2026Installation drawings label Intel 115X/1200 and 1700 and an AMD page. The manual predates the LGA1851 listing.

RAM height clearanceiAir coolers only. The tallest memory module that fits under the cooler with all included fans in their standard position. When the maker gives different values per socket, store the lowest and name the others in the source note. A heatsink that does not reach over the memory slots has no height limit, so the field is left out and the maker's statement goes in the source note.

Fans

Included fansiFans in the box that cool the heatsink or radiator, one row per fan model. A VRM fan on the pump block is left out. Speed, airflow, pressure and noise are the maker's figures for one fan at full speed, in the fastest mode and without a low-noise adapter. When a range is published, the top of the range is stored. Count is the number of rotors, so a unified frame with three 120 mm rotors counts 3 with size 120. Min speed is the lowest speed while spinning. A zero RPM stop is not stored. FDB and S-FDB are fluid dynamic. HDB is hydrodynamic. Cooler Master's Loop Dynamic Bearing is loop dynamic. If the maker gives airflow only in m³/h, convert with 1 m³/h = 0.5886 CFM, round to one decimal and say so in the source note. Connector is the fan's power lead. A separate lighting lead is not counted, and a maker cable or adapter in the box that ends in a 4-pin PWM plug counts as 4-pin PWM, even when the fan's own lead is proprietary. For an air cooler with one fan, the maker's noise figure for the cooler is the fan noise. A figure the maker does not label per fan or in total counts as per fan. When a maker table prints noise for the whole cooler with no per-fan label and the maker's own data sheet for the same fan gives a figure, the fan data sheet figure is stored.

The page does not say whether the 61 mm includes the 25 mm fan. Only width 122 (the fan frame is 120 mm wide) and height 156.2 are stored. APH Networks gives 81 mm for the axis along the airflow with the fan, so the depth is left out.

Heatsink dimensionsiAir coolers only. The heatsink without fans, as the maker lists it. Map by direction, not by letter. Width runs across the fins, depth runs along the airflow. DeepCool's 129 x 138 x 160 mm (L x W x H) is width 129, depth 138, height 160. A heatsink depth that equals the depth with fans includes the fan, so that axis is not stored.

WeightiAn air cooler with its included fans. An AIO cooler as one unit with pump block, tubes, radiator and fans. Mounting hardware is left out when the maker states it separately. When one maker figure may include the mounting kit, such as a press release net weight above the product page figure, the product page figure is stored. An RGB edition can weigh a little more or less, so it is per variant.
