An LGA 1151 board is a long-lived platform. It covers the Intel desktop generations that many people still run for office work, light gaming, and home servers, and it keeps the same mounting hole spacing as LGA 1150, 1155, and 1156. That is good news for upgraders, because a modern air cooler can often be bolted straight onto an older motherboard. The decision is less about whether a cooler fits and more about how much clearance, noise control, and heat capacity you need.
This 2026 guide helps owners of LGA 1151 systems pick a replacement or upgrade cooler, whether the chip is a modest dual-core or an unlocked processor that runs hot. We compare eight air coolers using only what their titles state, so you will see socket lists, fan sizes, heat pipe counts, and listed height rather than invented temperature figures.

How to Choose
Confirm the socket line and read it literally
Every cooler here lists LGA 1151 in its title. Some also list 1150, 1155, 1156, 1200, 1700, or 1851, which helps if you plan to move the cooler to a newer board later. Do not rely on a cooler that says only “Intel” without naming the socket. Look at the retention bracket you receive, since LGA 1151 uses the same four-hole pattern as the sockets around it. If you may upgrade to a newer Intel board within a year or two, a longer socket list in the title saves you from buying a second cooler.
Measure height before you buy
Tower coolers can clash with tall memory modules and with side panels. A listed 53mm height signals a low-profile unit for compact cases. Larger towers with 120mm or 130mm fans need more clearance, so look up your case’s CPU cooler height limit and measure the space around the first memory slot. A tall memory heatsink is the most common reason a tower will not seat properly.
Match heat capacity to your processor
A listed TDP such as 65W or 130W is the rough heat capacity of the cooler. LGA 1151 chips range from efficient parts to overclocking models, so choose a cooler with a comfortable margin above your processor’s listed power draw. More heat pipes and larger fans generally move heat better, while a basic heatsink fits only low-power chips. If the processor has run near its limit in your current setup, choose the larger tower and let the fan spin slower.
Think about fans, noise, and lighting
PWM fans change speed with temperature, which keeps idle noise down. A broad speed range, like 500 to 2400 RPM, gives headroom but can get loud at the top. ARGB lighting is cosmetic and needs a compatible header. Budget models usually skimp on fan quality and mounting hardware, so a cooler with named PWM fans is a safer path.
The 8 Best Options
Cooler Master i30
The i30 is an Intel-only cooler with a 92mm low-noise fan and a heatsink, listed for LGA 1150, 1151, 1155, and 1156. Its title is the most direct about older sockets, which makes it an easy fit for a classic build that needs a straightforward replacement. It reads as a step up from a stock design rather than a high-end tower, and it keeps the shopping decision simple for someone refreshing an aging office or family PC.
- Strength: explicit LGA 1150/1151/1155/1156 support.
- Strength: a low-noise 92mm fan.
- Trade-off: no heat pipe count or TDP is listed, so capacity is unclear.
Skip it if you plan to move the cooler to a newer socket or a hot processor.
Thermalright Assassin X120 Refined SE
This single-tower cooler lists four heat pipes, a TL-C12C PWM fan, an aluminum heatsink cover, and AGHP technology. Its socket list includes AM4, AM5, and Intel LGA 1150, 1151, 1155, 1200, 1700, and 1851, so the same cooler can follow you through several platform upgrades. It suits a mid-range LGA 1151 build where quiet fan control matters and a full dual-tower is more than the chip needs.
- Strength: a wide socket list across Intel and AMD.
- Strength: four heat pipes and a PWM fan.
- Trade-off: tower size means checking memory and case clearance.
Skip it if your case is slim.
Thermalright Peerless Assassin 120 SE
This dual-tower cooler lists six heat pipes with AGHP technology, two 120mm PWM fans, and a 1550RPM speed. It is the heaviest-duty option for an overclocked or unlocked LGA 1151 processor, and its socket list also covers AM4, AM5, and newer Intel sockets. The title does not give a TDP, but the heat pipe count and twin fans point to the highest capacity on the list, and the fan speed ceiling is moderate.
- Strength: six heat pipes and dual 120mm PWM fans.
- Strength: a wide socket list for future upgrades.
- Trade-off: it is the biggest unit here and takes the most space.
Skip it if clearance is tight or the processor is a low-power part.
Thermaltake UX150 ARGB
The UX150 has a copper base, aluminum fins, a 130mm PWM fan running 500 to 2400 RPM, an Infinity Mirror ARGB design, and a 130W TDP. The socket list covers LGA 1851, 1700, 1200, 1156, 1155, 1151, and 1150, so it suits builders who want lighting plus a clear heat capacity figure to compare against their processor. It is Intel only, which narrows later reuse.
- Strength: a stated 130W TDP.
- Strength: ARGB lighting with a wide RPM range.
- Trade-off: the top fan speed can be loud, and the lighting needs a header.
Skip it if you dislike RGB or want AMD support.
Thermalright AXP-90 X53
This low-profile cooler lists a 90mm TL-9015 PWM fan, four heat pipes, and a 53mm height. Sockets include AM4 and Intel LGA 1150, 1151, 1155, 1851, and 1200. It targets compact cases and home theater builds where taller towers will not fit, and the title describes the fan as quiet. Four heat pipes in so short a body make it the most interesting small-form-factor choice here.
- Strength: 53mm height for small cases.
- Strength: four heat pipes in a low-profile package.
- Trade-off: a smaller fan and low profile limit capacity compared with towers.
Skip it if you have a hot processor and a roomy case.
Copper Core Aluminum Heatsink
A basic heatsink and fan with a copper core, it names Intel Core i3, i5, and i7 chips and lists LGA 1200, 1151, 1150, 1155, and 1156 along with a 65W ceiling. It is the simplest option here and fits a light office PC or a replacement for a worn stock cooler. Because the title gives no brand-level detail, treat it as a functional swap rather than a performance upgrade.
- Strength: LGA 1151 named alongside a clear 65W limit.
- Strength: a simple design for low-power chips.
- Trade-off: no heat pipes or fan model are listed.
Skip it if your processor draws more than the listed limit.
Thermalright AXP-90 X53 Black
This black version of the AXP-90 X53 lists a TL-9015B low-profile PWM fan, four heat pipes, 53mm height, and sockets that include AM4 and Intel LGA 1150, 1151, 1155, 1156, 1200, and 1851. It is for the same compact builds, with a darker look that suits a windowed case or a blacked-out parts list, and it explicitly adds LGA 1156.
- Strength: adds LGA 1156 to the socket list.
- Strength: low-profile height and PWM fan control.
- Trade-off: it shares the low-profile capacity limits of the standard model.
Skip it if you need a tall tower for a hot chip.
Thermaltake UX150-L ARGB
The UX150-L carries a different part number but lists the same copper base, aluminum fins, 130mm PWM fan, 500 to 2400 RPM range, Infinity Mirror design, and 130W TDP as the UX150. It covers the same Intel socket list. Treat it as an alternate listing when stock of the other model runs out, or when a retailer carries only one part number.
- Strength: matching specs to the UX150.
- Strength: wide Intel socket support including 1151.
- Trade-off: the title does not explain what the L suffix changes.
Skip it if you want a non-lit cooler.
Which One Fits Your Situation
You have a slim case or a home theater PC
Choose the Thermalright AXP-90 X53 or its black version, because the 53mm height is the whole point. Measure the vertical gap between the socket and the side panel first so the listed height clears with room to spare.
You run a hot unlocked processor
The Thermalright Peerless Assassin 120 SE brings six heat pipes and two fans, the strongest cooling hardware listed.
You want a quiet, simple upgrade
The Cooler Master i30 is the plainest replacement, while the Thermalright Assassin X120 Refined SE adds more heat pipes and a socket list that carries over to newer boards. The Copper Core Aluminum Heatsink only suits a low-power chip.
You like lighting and a stated TDP
The Thermaltake UX150 ARGB gives you a 130W figure and addressable lighting, and the UX150-L is the same design under another part number if that listing is easier to find.
Common Mistakes
- Choosing a cooler that lists only “Intel” with no socket named.
- Ignoring memory clearance next to the CPU socket, especially with tall heat-spreader modules installed.
- Pairing a 65W-class heatsink with a high-power unlocked chip.
- Forgetting that ARGB needs a compatible header or controller.
- Assuming a taller tower always means a quieter system; fan speed curves and the number of fans matter just as much as height.

Frequently Asked Questions
Are LGA 1150 coolers compatible with 1151?
Mounting hole spacing is shared across several of these sockets, which is why titles list them together. Always confirm the exact socket in the title.
Do I need thermal paste?
Many coolers include some, but it is smart to confirm the contents or keep a spare tube on hand. Clean the old compound from the processor surface before mounting the new cooler.
Is a low-profile cooler enough for a 65W chip?
For light work it generally can be, but check the listed capacity and case airflow before relying on one.
Can I reuse the cooler on a newer board?
Some titles list LGA 1200, 1700, or 1851 and AMD sockets, which makes reuse possible, subject to the included brackets. Keep the original hardware bag somewhere safe in case you move boards later.
