The description claims consistent cooler contact and does not quote any measured temperature reduction. So a lower reading is a possible outcome rather than a stated one. Whether your build improves depends on how well the cooler was seated to begin with.
A hotter-than-expected CPU reading is the moment most people reach for a CPU contact frame and expect a number on the box to back it up. The AsiaHorse Pulsar carries no such number. What it carries is a design claim about even contact, and the difference between a claim and a guarantee matters before you spend anything on the fix.
No, the Pulsar frame is not sold with any promised temperature drop. AsiaHorse describes it as spreading mounting pressure evenly across the die for consistent cooler contact, priced at R299, but that is a mechanical description rather than a measured result. Whether your own AM5 build runs cooler afterwards depends on how uneven the original mounting was.
Read the product description closely and you will notice it never states a degree figure. It talks about clamping force spread across the chip, aimed at giving the cooler a flatter, more even seat than the stock AM5 retention arms manage on their own. That is a mechanical claim about geometry, not a thermal claim about outcomes. A part can do exactly what it is designed to do - press evenly - and still produce a result close to zero, if the original mount was already close to even.
This distinction gets lost quickly once a product lands in a cart. Buyers see "consistent cooler contact" and mentally round it up to "lower temperatures," which is a reasonable but unsupported leap. The honest reading is: better geometry is possible, better numbers are not promised.
Two identical AM5 boards running the same cooler can react differently to this frame, because the starting condition is not identical. If board A had a slight twist in its stock retention bracket, unevenly loading one side of the integrated heat spreader, swapping to a frame designed to spread pressure evenly could measurably help. Board B, with a bracket that was already applying fair, even pressure, has much less room to improve, and the reading may barely move.
This is also why online results for products like this one are so scattered - forum posts describing a big drop next to others describing almost nothing are both plausible, because they are describing different starting points, not different parts. Cooler capacity and case airflow matter here too: a cpu cooler that is already undersized for the chip will not suddenly perform like a bigger unit just because the mounting improved.
If you want an honest answer for your own system rather than a general one, the process is straightforward. Load the CPU with a fixed, repeatable task and note the peak and sustained temperature, along with the room conditions and fan curve at the time. Fit the frame following the included instructions, using fresh thermal solutions since the job requires removing the cooler anyway. Run the identical workload again under the same conditions and compare.
Keep the fan curve and ambient temperature constant between the two tests, because either one can shift the reading by several degrees on its own, swamping whatever the frame contributed. A five degree change from a warmer room has nothing to do with the mounting hardware.

Builds where contact was uneven to begin with, since that is the condition the frame is designed to address.
By recording temperatures under a fixed workload before and after, changing nothing else at the same time.
It does, since fresh paste goes on during the job and may account for part of any improvement seen.
Only by doing them in two sessions - re-pasting first and testing, then fitting the frame afterwards and testing again.
That depends on whether contact was really your limiting factor, which the temperatures recorded before the job help answer.
