Thermal Grizzly has added Intel’s Core Ultra 7 270K Plus to its TG Delidded CPU lineup, giving custom-loop builders a pre-delidded Arrow Lake option with Thermal Grizzly’s own warranty coverage.
This is not a normal boxed CPU purchase. The appeal is narrow: a buyer gets a processor that Thermal Grizzly says has already gone through delidding, cleaning, light die surface treatment and validation, though those preparation details should be treated as the company’s own claim rather than independently verified testing.
The listed price is $525.33 including VAT, plus shipping, according to the product listing, but buyers should check the store page directly because pricing and availability can change quickly. Intel’s recommended customer price for the standard Core Ultra 7 270K Plus has been reported at $289 to $299, though that comparison is best treated as a reference point rather than a confirmed street-price match.
Quick Comparison
| Image | Product | Best fit | Link |
|---|---|---|---|
 |
Intel Core Ultra 7 270K Plus | Builders who do not need direct-die cooling should compare against the standard Intel Core Ultra 7 270K Plus first. It keeps the normal boxed-CPU path and avoids the mounting restrictions of a pre-delidded chip. | Check Price on Amazon |
 |
Thermal Grizzly Intel 1851 Mycro Direct-Die Pro | A direct-die CPU like this needs a compatible block rather than a normal cooler mount. This LGA1851-focused Mycro Direct-Die Pro is the most contextually relevant cooling hardware for the build type discussed here. | Check Price on Amazon |
 |
Thermal Grizzly Conductonaut Extreme | Direct-die setups usually pair the exposed silicon with liquid metal rather than conventional paste. Conductonaut Extreme fits that use case, but it must be handled carefully because it is electrically conductive. | Check Price on Amazon |
 |
Thermal Grizzly TG Shield | Liquid metal work around exposed CPU components benefits from insulation or protective coating. TG Shield is relevant for builders preparing the area around a delidded CPU before applying conductive thermal interface material. | Check Price on Amazon |

What Thermal Grizzly Is Actually Selling
The Core Ultra 7 270K Plus is an LGA1851 desktop processor from Intel’s Arrow Lake family. Intel’s published specifications list a 24-core configuration made up of 8 Performance cores and 16 Efficient cores, with 24 threads, boost clocks up to 5.5GHz, 36MB of Intel Smart Cache, 40MB of L2 cache, 125W base power and 250W maximum turbo power.
Thermal Grizzly’s version is aimed at direct-die cooling, where the cooler contacts the processor dies more directly instead of relying on the factory integrated heatspreader. That approach can reduce the thermal barrier between the silicon and the cooling loop, but it also raises the stakes for installation pressure, mounting accuracy and component compatibility.
The company claims that removing the heatspreader and pairing liquid metal with a direct-die water block can reduce load temperatures by up to 22°C, depending on the loop, radiator capacity and overall setup. That figure is a vendor claim, not an independent result, so it should be read as a best-case marketing target rather than a guaranteed outcome.
Specs and Price Context
For buyers, the key question is not whether the chip is faster on paper than the standard retail CPU. It is whether the extra cost and setup risk make sense for a cooling-focused build.
| Item | Details from the source material |
|---|---|
| CPU | Intel Core Ultra 7 270K Plus |
| Socket | LGA1851 |
| Core layout | 24 cores: 8 Performance cores and 16 Efficient cores |
| Threads | 24 |
| Boost clock | Up to 5.5GHz |
| Cache | 36MB Intel Smart Cache, 40MB L2 cache |
| Power | 125W base power, 250W maximum turbo power |
| Thermal Grizzly listing | $525.33 including VAT, plus shipping, according to the store listing |
| Intel recommended customer price | Reported as $289 to $299 for the standard CPU |
That table explains why this is a specialist product. A standard Core Ultra 7 270K Plus is the baseline. Thermal Grizzly’s version adds preparation work, validation and a warranty path for a CPU that would normally lose Intel warranty coverage once delidded.
The Warranty Is the Main Practical Difference
Delidding normally creates a warranty problem. Once the integrated heatspreader is removed, the processor is no longer in factory condition, and the risk shifts heavily toward the user. Thermal Grizzly is trying to make that tradeoff less awkward by selling a prepared CPU under its own warranty terms.
Each processor is described as being tested after preparation, and the package is said to include a USB flash drive with a test screenshot and microscope image of the delidded processor. Those details are useful for buyers because they create a basic record of the unit’s condition at the time it leaves Thermal Grizzly, but they do not remove the need for careful installation.
There is also a major restriction around the original heatspreader. Thermal Grizzly says the original heatspreader must not be used with this CPU. The stock heatspreader is included, but using it is said to void Thermal Grizzly’s warranty because the height difference between the dies and the original heatspreader may cause damage. That restriction comes from Thermal Grizzly’s terms and should be treated as a critical setup warning.
Who This CPU Makes Sense For
This is not the version most Core Ultra 7 buyers should choose. It is for builders who already intend to use direct-die cooling and want to avoid doing the delid themselves. That means the rest of the system needs to be chosen around the CPU, not the other way around.
It makes the most sense for:
- Custom-loop builders using a compatible direct-die water block.
- Overclocking-focused users who are willing to trade simplicity for lower temperatures.
- Buyers who want a delidded CPU but prefer a vendor-prepared unit with Thermal Grizzly warranty coverage.
- Systems where CPU load temperature is a real constraint, not just a cosmetic benchmark target.
It makes less sense for:
- Anyone planning to use a standard air cooler or normal AIO mounting setup.
- Buyers who want a simple install with typical boxed-CPU warranty expectations.
- Value-focused users comparing only CPU performance per dollar.
- Builders who may later want to reinstall the original heatspreader.
The price premium is the hard part. If the buyer only wants the CPU, the standard retail chip is the cleaner choice. If the buyer was already budgeting for direct-die cooling hardware, liquid metal, careful mounting and loop tuning, Thermal Grizzly’s version may be easier to justify.
Verdict: Useful, Expensive and Very Specific
Thermal Grizzly’s delidded Core Ultra 7 270K Plus is best viewed as a convenience and risk-management product for a small group of PC builders. It does not turn the Core Ultra 7 270K Plus into a different class of processor, and it does not make direct-die cooling simple. What it offers is a prepared CPU, a vendor-backed warranty path and a clearer route into a cooling setup that many users would not want to attempt from scratch.
For most buyers, the standard Core Ultra 7 270K Plus remains the sensible option. For direct-die cooling enthusiasts who already understand the mounting and compatibility requirements, Thermal Grizzly’s version is a more controlled way to buy into the experiment.
