Searching for 1151 CPU coolers YouTube reviews is a smart move before upgrading an older Intel PC, because video shows mounting steps and fan noise in a way spec sheets cannot. The catch is that test methods vary widely. This guide explains what a useful cooler video shows, which red flags to skip, and which verified LGA 1151 coolers to look up.
Quick answer
A good YouTube cooler review states the test CPU and its power, the room temperature, and compares coolers at the same noise level. For LGA 1151, it should also show the 115x mounting kit. If you only want a shortlist, start with the Thermalright Peerless Assassin 120 SE and the Noctua NH-U12S redux.

What useful 1151 CPU coolers YouTube reviews show
Cooler reviews differ more in method than in production quality. A polished video with vague testing tells you less than a plain one with clear numbers. These four checks separate useful reviews from entertainment, and they matter most on older platforms like LGA 1151, where many videos were made years ago with different hardware.
The test CPU and its power draw
Look for the exact processor and how much power it drew during the test. An LGA 1151 Core i7-7700K is rated at 91W and a Core i9-9900K at 95W TDP, but motherboards often let K chips boost above that, so a reviewer who states measured or limited power gives you a usable reference.
Results from a modern 250W-class chip do not translate directly to a four-core LGA 1151 processor. If the video tests a different CPU, focus on how coolers rank against each other at a similar heat load, not on the absolute temperatures shown on screen.
Room temperature and repeatable runs
A useful review states the ambient room temperature, or reports results as temperature above ambient. Without that, a 3°C difference between two coolers could simply be a warmer afternoon. Repeated runs, or at least a note that results were checked, add confidence.
Also watch how long the load ran. Short bursts mostly show how quickly a heatsink soaks up heat, while longer sustained loads show its real capacity. For gaming-focused LGA 1151 systems, both views are useful, but they answer different questions.
Noise-normalized comparisons
The most useful comparisons test coolers at the same noise level, not just at full fan speed. A cooler that wins at 100% fan speed might lose when every fan is set to a quiet level, which is how most people run their PCs day to day, gaming or working.
If a video only shows full-speed results, look for its noise readings and how they were measured, such as distance from the case. Manufacturer decibel ratings are measured in different ways by each brand, so a consistent reviewer measurement is more useful than spec sheet numbers.
Mounting on an LGA 1151 board
For LGA 1151, a review that shows the Intel backplate, standoffs and brackets is worth more than one that only shows an AMD install. LGA 1151 uses a 75 x 75mm hole pattern shared with LGA 1150, 1155, 1156 and 1200, while LGA 1700 moved to a 78 x 78mm pattern.
That means a video filmed on an LGA 1700 board may show different brackets from the ones you will use. Pause on the parts layout to confirm the cooler includes 115x hardware, and check the listing before buying, since kits change between production runs.
Red flags in cooler videos
Not every popular video is a reliable buying guide. These warning signs do not make a review worthless, but they should make you look for a second source before spending money, especially on a premium cooler you plan to keep for years or carry to a new build.
Missing test details
Be wary of videos that show a temperature chart without naming the CPU, its power, the case or the room temperature. Without those details you cannot compare the result with any other review, or with your own system and case at home. Missing fan speeds are a warning sign too.
The same applies to results shown only as a single number at the end. A short summary is fine, but a good reviewer will explain how they reached it. If the method is hidden, treat the conclusion as an opinion rather than a measurement.
Undisclosed sponsorship or affiliate pressure
Sponsorship is common and not a problem in itself, but it should be disclosed clearly. If a video pushes a buy link early and spends little time on testing, weigh its verdict lightly and compare it with independent text reviews or other videos from different channels.
Our own rule is the same: rankings here follow verified specs and fit, never commission. When a video’s recommendation matches several independent sources and the published specs, it is far more trustworthy than a single enthusiastic endorsement.
Old videos with outdated mounting kits
Many LGA 1151 cooler videos date from 2016 to 2019. Products have changed since then, with new revisions, different fans and updated brackets. A cooler shown in an old video may now ship with different hardware or a different model name and packaging.
Before buying, compare the model name and revision in the video with the current listing. For example, the original Cooler Master Hyper 212 Black Edition (RR-212S-20PK-R1) listed LGA 1151 but not LGA 1700, while the newer Hyper 212 Spectrum V3 lists both.
Verified LGA 1151 shortlist
These five coolers all list LGA 1151 or LGA 115x support, with specs confirmed against manufacturer pages or Amazon listings collected on November 11, 2026. Use them as search terms when looking for video reviews, then compare what you see against the verified specs below. Prices are a snapshot from Amazon US as of November 2026.
Thermalright Peerless Assassin 120 SE
This dual tower is the value pick for six- and eight-core LGA 1151 chips such as the Core i7-8700K and i9-9900K. Thermalright lists a 125 x 110 x 155mm heatsink, six 6mm heat pipes and TL-C12C 120mm fans at 1,550 RPM and 25.6 dBA, and the Amazon listing confirms two fans and LGA 115x support.
It was listed around $35 on Amazon US and rated 4.7 out of 5 from about 3,400 ratings as of November 2026. When watching reviews, check that the reviewer’s case clears 155mm and note any RAM clearance comments, since its front fan can sit over tall memory.
- Pros: dual-tower capacity for a low price; LGA 115x through LGA 1851.
- Cons: 155mm height; warranty not stated on the page we checked.
Cooler Master Hyper 212 Spectrum V3
The Hyper 212 Spectrum V3 suits 65W chips such as the Core i7-8700 and lightly loaded four-core K chips. Cooler Master lists 124 x 73 x 152mm, four heat pipes and a 120mm ARGB fan from 650 to 1,750 RPM, with LGA 1151 named explicitly and a two-year warranty.
It was listed around $20 on Amazon US and rated 4.7 out of 5 from about 990 ratings as of November 2026. Older Hyper 212 videos may show earlier models, so make sure the review covers the Spectrum V3 and its redesigned brackets.
- Pros: low price; LGA 1151 named; ARGB.
- Cons: single fan; limited headroom for eight-core chips.
Noctua NH-U12S redux
The NH-U12S redux is the quiet, mid-priced pick for four- and six-core LGA 1151 chips. The listing gives a 158mm height, one NF-P12 redux-1700 120mm fan, NT-H1 paste and SecuFirm2 mounting for LGA 1851, 1700, 1200 and 115x, plus a six-year warranty from Noctua.
It was listed around $60 on Amazon US and rated 4.8 out of 5 from about 4,440 ratings as of November 2026. When comparing videos, note that the redux uses a different fan from the standard NH-U12S, so results for one do not exactly apply to the other.
- Pros: quiet; six-year warranty; slim design that clears RAM.
- Cons: single fan; less headroom than dual towers.
Noctua NH-D15
The NH-D15 suits quiet, high-capacity LGA 1151 builds with a Core i9-9900K. The listing describes six heat pipes, two NF-A15 140mm fans, SecuFirm2 mounting for LGA 115x and newer sockets, and a six-year warranty. A retailer lists 165mm and Amazon 168mm, so plan for 168mm.
It was listed around $110 on Amazon US and rated 4.8 out of 5 from about 11,600 ratings as of November 2026. Because it has been reviewed for many years, check the video date and make sure you are not watching coverage of the newer NH-D15 G2, which is a different cooler.
- Pros: high capacity with low noise; long-proven mounting.
- Cons: tall and wide; expensive.
Thermalright Aqua Elite 240 V3
The Aqua Elite 240 V3 is the budget liquid option for LGA 1151 cases with a 240mm mount. Thermalright lists TL-C12B-S V2 120mm fans, a 2,800 RPM pump at 23 dBA, a three-year warranty and support for LGA 115X through 1851, plus AM4 and AM5 on the AMD side.
It was listed around $45 on Amazon US and rated 4.7 out of 5 from about 500 ratings as of November 2026. In videos, listen for pump noise at idle, which spec sheets describe only roughly, and check how the reviewer mounted the radiator relative to the pump.
- Pros: low-cost 240mm AIO; three-year warranty.
- Cons: radiator dimensions not stated in text; adds a pump.
FAQ
These answers cover common questions about using video reviews to choose an LGA 1151 cooler. They rely on the verified socket data and specs used throughout this guide. We have not cited specific channels or videos, because their content and test methods change over time.
Are 1151 CPU coolers YouTube reviews reliable?
Some are very reliable and some are not. The useful ones state the CPU, its power, the room temperature and noise levels, and show the mounting hardware. Compare at least two independent sources, and check their conclusions against the cooler’s published specs.
Should I trust old videos for LGA 1151 coolers?
Use them with care, and always check the upload date. Many date from the LGA 1151 era and may cover older revisions with different fans or brackets. Confirm that the model name and revision match the current listing, and that the box still includes LGA 115x mounting hardware.
Do coolers tested on LGA 1700 apply to LGA 1151?
Partly. Rankings between coolers usually carry over, but absolute temperatures depend on the CPU’s heat output, and LGA 1700 chips can draw far more power than LGA 1151 ones. The mounting hardware also differs, since LGA 1700 uses a 78 x 78mm pattern.
Conclusion
Use YouTube to see mounting steps and hear real fan noise, but trust only videos that state the CPU, its power, room temperature and noise levels. For most LGA 1151 PCs, the Thermalright Peerless Assassin 120 SE is the best cooler to look up and buy; choose the Noctua NH-U12S redux if quiet operation matters more.
