Choosing the best CPU coolers for LGA 1700 is easier when you start from the chip in your socket, not from a generic top-ten list. This Division Gaming guide matches eight air and liquid coolers to 12th, 13th and 14th gen Core i5, i7 and i9 processors. You get a clear shortlist, the mounting facts that matter and fewer return trips.
Best CPU coolers for LGA 1700 by Core i5, i7 and i9 tier
The short answer: a Core i5 non-K runs happily on the Thermalright Assassin X 120 Refined SE, a Core i5 K pairs well with the Peerless Assassin 120 SE or Arctic Freezer 36, a Core i7 suits a Phantom Spirit 120 SE or Noctua NH-D15 G2, and a Core i9 deserves a 360mm AIO like the Arctic Liquid Freezer III 360.
That tiered approach matters because LGA 1700 spans chips from 65W base TDP up to 253W turbo limits. A Core i5-12400 and a Core i9-14900K share the same socket, yet need very different heat sinks.
The table below summarizes our eight picks for the best CPU coolers for LGA 1700, grouped by the processor tier they suit best.
| Cooler | Type | Fans / radiator | Height | Best for | Noise note |
|---|---|---|---|---|---|
| Thermalright Assassin X 120 Refined SE | Single tower | 1 x 120mm | 148mm | Core i5-12400/13400/14400 | Quiet at gaming loads |
| ID-Cooling SE-224-XTS | Single tower | 1 x 120mm | 154mm | Core i5 non-K, Core i3 | Mild hum at full speed |
| Thermalright Peerless Assassin 120 SE | Dual tower | 2 x 120mm | 155mm | Core i5-13600K/14600K | Calm under gaming |
| Arctic Freezer 36 | Single tower, push-pull | 2 x 120mm | 159mm | Core i5 K, Core i7 non-K | Low-pitched |
| Thermalright Phantom Spirit 120 SE | Dual tower | 2 x 120mm | 154mm | Core i7-13700K/14700K | Quiet for its class |
| Noctua NH-D15 G2 | Dual tower | 2 x 140mm | 168mm | Core i7 K, tuned Core i9 | Very quiet |
| Arctic Liquid Freezer III 360 | AIO | 360mm | Radiator 38mm thick | Core i9-13900K/14900K | Quiet at mid speed |
| Corsair iCUE H150i Elite (360mm) | AIO | 360mm | Radiator 27mm thick | Core i9 with RGB build | Moderate |
Pick from the row that matches your processor, then confirm your case clearance before checkout.
How LGA 1700 changes cooler mounting
LGA 1700 arrived with Intel’s 12th gen Alder Lake in late 2021. Its mounting holes moved to a 78 x 78mm pattern, compared with 75 x 75mm on LGA 1151 and LGA 1200.
The socket stack is also slightly shorter. That is why older coolers often need new standoffs or a dedicated bracket, even when the holes look close.
Most coolers sold since 2022 include LGA 1700 hardware in the box. Noctua offers its NM-i17xx-MP78 kit for older models, and other brands provide similar upgrade brackets.
Good news for future upgrades: LGA 1851 for Core Ultra 200S uses the same hole spacing. A cooler that fits LGA 1700 generally mounts on LGA 1851 with the same hardware.
So before reusing an older heat sink, check the maker’s compatibility page for an LGA 1700 kit.
The ILM bending issue and contact frames
Some LGA 1700 boards show slight CPU bending caused by the stock independent loading mechanism (ILM). This can leave a small gap at the heat spreader’s center and raise temperatures by a few degrees.
Aftermarket contact frames, such as Thermalright’s LGA1700-BCF, replace the stock ILM and spread the pressure more evenly. Arctic’s Liquid Freezer III includes its own contact frame in the box.
A contact frame is optional, not mandatory. Treat it as a cheap tweak for hot Core i7 and i9 chips rather than a fix you must apply.
How we chose these LGA 1700 coolers
In our research we compared manufacturer spec sheets, socket compatibility lists and independent reviews from outlets that publish repeatable thermal testing. We also weighed long-term owner feedback on noise, mounting quality and fan bearing life.
We did not run our own lab tests. Our full method is described on the how we review page.
Each pick had to ship with native LGA 1700 mounting, stay widely available in the US in 2026 and fit at least one common case size. That keeps the list practical rather than theoretical.
Coolers for Core i5 non-K and Core i3 chips
Chips like the Core i5-12400, i5-13400 and i5-14400 carry a 65W base power. Their turbo power peaks well above that, but they rarely sustain it in games.
A single 120mm tower is plenty here. Spending more brings little extra performance for these locked processors.
Thermalright Assassin X 120 Refined SE
The Assassin X 120 Refined SE is a compact single tower with four 6mm heat pipes and a single 120mm fan. At 148mm tall, it fits many slim mid-towers that reject 155mm coolers.
Our research found it is often under $25, which makes it a strong match for budget Core i5 builds.
Here is how it stacks up:
- Pro: 148mm height fits tighter cases
- Pro: Includes LGA 1700 and AM5 mounting
- Pro: Very low price for the cooling it offers
- Con: Four heat pipes limit headroom for K-series chips
- Con: Basic styling with no premium finish
It is the easy default when you want reliable cooling without fuss.
ID-Cooling SE-224-XTS
The SE-224-XTS is another single 120mm tower, standing 154mm tall. It uses four heat pipes with direct contact and a black top cover.
Owners often praise its clean look for the price. It suits Core i3 and Core i5 non-K builds where a little extra visual polish matters.
A quick view of the trade-offs:
- Pro: Tidy look with a top cover
- Pro: Simple mounting process
- Con: Fan can hum when it ramps up
- Con: Less headroom than dual-tower designs
Either single tower covers these chips well, so let price and looks decide.
Coolers for Core i5 K-series processors
The Core i5-13600K and i5-14600K have a 181W maximum turbo power. They respond well to a step up in heat sink mass.
A dual-tower or push-pull air cooler is the sweet spot. You get noticeably more headroom without paying AIO prices.
Thermalright Peerless Assassin 120 SE
The Peerless Assassin 120 SE uses two fin stacks, six heat pipes and two 120mm fans. It stands 155mm tall and is usually in the $35 to $45 range, though prices change.
It became a community favorite because it trades blows with coolers that cost twice as much. For a Core i5 K, it is one of the safest value picks.
Key strengths and weaknesses:
- Pro: Excellent cooling per dollar
- Pro: Includes LGA 1700 and LGA 1851 hardware
- Con: Wide fin stacks can crowd tall RAM in the first slot
- Con: Packaging and manual are basic
Check RAM height clearance before you order, and it will serve you well.
Arctic Freezer 36
The Arctic Freezer 36 is a single tower with two P12 Pressure-optimised fans in push-pull. It stands 159mm tall and uses direct-touch heat pipes.
Its mount supports Intel LGA 1700 and LGA 1851 plus AMD AM4 and AM5. Note that it does not cover older Intel sockets like LGA 1200.
What to expect:
- Pro: Push-pull fans in a slim single-tower footprint
- Pro: Clean, low-pitched fan sound
- Con: 159mm height rules out some compact cases
- Con: No support for legacy Intel sockets
It is a smart pick if you value a narrow tower that leaves RAM slots clear.
Coolers for Core i7 K-series processors
The Core i7-13700K and i7-14700K can pull up to 253W under Intel’s default profile. All-core workloads push them hard, though gaming loads are far lower.
A large dual tower handles them in gaming builds. For long renders, consider an AIO from the next section.
Thermalright Phantom Spirit 120 SE
The Phantom Spirit 120 SE uses seven heat pipes, two fin stacks and two 120mm fans. It is 154mm tall, so it clears most mid-towers.
Reviews consistently place it near much pricier air coolers. It is a strong Core i7 choice if you want air cooling and a modest budget.
A summary of its trade-offs:
- Pro: Seven heat pipes for higher heat loads
- Pro: Good value against premium dual towers
- Con: Heavy, so handle the board carefully during mounting
- Con: Fans get audible at full speed in heavy rendering
It brings near-flagship air cooling to a mid-range price.
Noctua NH-D15 G2
The Noctua NH-D15 G2 launched in 2024 as the successor to the famous NH-D15. It stands 168mm tall with two 140mm fans and eight heat pipes.
Noctua sells three base versions, including variants tuned for LGA 1700 bending and a high-base option. Pick the version Noctua recommends for Intel boards.
Pros and cons at a glance:
- Pro: Among the strongest air coolers available
- Pro: Very quiet and backed by a long warranty
- Con: 168mm height needs a roomy case
- Con: Premium price, often above $140
If your case fits it, this is the air cooler to beat for a Core i7 K.
Liquid coolers for Core i9 on LGA 1700
The Core i9-13900K and i9-14900K are the hottest chips on the platform. A 360mm AIO gives them the most consistent headroom in all-core loads.
Remember that these chips also had a 2024 instability issue tied to voltage. Intel released microcode updates, so update your BIOS before judging any cooler.
Arctic Liquid Freezer III 360
The Liquid Freezer III 360 uses a thick 38mm radiator and three P12 fans. It also ships with an LGA 1700 contact frame and offset mounting options.
Reviewers often rank it among the best-performing 360mm AIOs for the money. A small VRM fan on the pump block helps keep board power stages cooler.
Strengths and drawbacks:
- Pro: Thick radiator for strong heat dissipation
- Pro: Contact frame included for LGA 1700
- Con: 38mm radiator plus fans needs extra case clearance
- Con: Integrated cables can feel less flexible
It is the most complete package for a Core i9 that runs heavy workloads.
Corsair iCUE H150i Elite
Corsair’s H150i Elite line pairs a 360mm radiator with RGB fans and a lit pump cap. It suits builders who already use iCUE for lighting and fan control.
Cooling is strong, though value lags behind Arctic. Pick it when software integration and looks matter as much as temperatures.
Quick pros and cons:
- Pro: Polished lighting and software ecosystem
- Pro: Thin 27mm radiator eases top-mount clearance
- Con: Higher price than similar-performing AIOs
- Con: Software required for full control

Steps to check fit before you buy
A cooler that does not fit is the most common return reason. Follow these steps before you order any of the best CPU coolers for LGA 1700.
- Find your case’s maximum CPU cooler height on its spec page and subtract a few millimeters for margin.
- Check your RAM height, especially tall RGB kits that can clash with dual-tower fins.
- Confirm the cooler lists LGA 1700 in its compatibility chart, not just “Intel”.
- For AIOs, check radiator support at the top or front, including thickness with fans.
- Note where your VRM heat sinks and PCIe slot sit relative to the cooler’s footprint.
- Plan fan orientation so the cooler exhausts toward a rear or top case fan.
Five minutes of measuring now saves you a frustrating rebuild later.

LGA 1700 cooler FAQ
These are the questions LGA 1700 builders ask most often when picking a cooler.
Do LGA 1200 coolers fit LGA 1700?
Not directly. LGA 1700 uses 78 x 78mm hole spacing and a different socket height, so you need an LGA 1700 bracket or kit from the cooler maker.
Is an air cooler enough for a Core i9-14900K?
A large dual tower handles gaming loads well, but sustained all-core work can hit thermal limits. A 360mm AIO gives more headroom for heavy rendering.
Will an LGA 1700 cooler fit LGA 1851?
Generally yes. LGA 1851 for Core Ultra 200S uses the same mounting hole pattern, so most LGA 1700 coolers fit with the same hardware.
Do I need a contact frame for LGA 1700?
No, it is optional. A contact frame can reduce CPU bending and lower temperatures by a few degrees, which mostly helps hot Core i7 and i9 chips.
What cooler suits a Core i5-13400?
A single 120mm tower such as the Thermalright Assassin X 120 Refined SE is enough. The chip has a 65W base power and rarely sustains high loads in games.
