RAKSTORE T129215SU 85mm グラフィックスカード冷却ファン Powercolor RX 6600 6600XT Fighter Quiet Cooler Fan 交換用

The RAKSTORE T129215SU is a service part: a single replacement fan for the stock cooler on the PowerColor RX 6600 Fighter and RX 6600 XT Fighter. Buying it means committing to a repair rather than a card upgrade.

Overview

The listed specs are an 85mm fan diameter, a 4-pin header connector, 12V operation, forced-air cooling, metal construction, and a quantity of one fan. It is designed to take PWM control from the card's own fan controller, so it is not a general-purpose case fan — the screw positions and shroud fit are model-specific.

This part suits owners of a three- or four-year-old RX 6600 Fighter that rattles at idle, has one fan that no longer spins, or develops bearing noise under load. It does not suit anyone shopping for better cooling or lower noise.

The goal is restoring factory behavior, nothing beyond it.

T129215SU is a widely circulated GPU fan designation, and several sellers offer parts under the same number. RAKSTORE is one of them; the manufacturer and brand fields both point to RAKSTORE, consistent with the product title.

Why Replacement Fans Fail in the First Place

Most GPU fan failures come down to bearing wear and dried lubricant. The GPU die and heatsink are usually fine — a small rotating part simply reaches end of life and takes the whole card out of service.

Given what an RX 6600 is worth used, scrapping a card over a fan is a poor trade.

The catch is that third-party service parts carry risks an OEM part does not. Rated RPM, static pressure, bearing type, and cable length are not published for this listing, so identical behavior to the original is not guaranteed.

A slower fan means higher load temperatures; a faster one means it will not be quiet.

Set expectations accordingly: "close to stock" is success, and "it spins reliably" is the minimum bar. With that framing, the caveats below make sense.

Compatibility Guide

Only two models are listed as compatible: the PowerColor RX 6600 Fighter and the RX 6600 XT Fighter. The compatibility notes explicitly exclude the Red Devil Edition.

Fighter and Red Devil use different cooler designs, fan sizes, and shroud mounting points, so buying on the RX 6600 XT name alone will fail.

Quantity is the easiest thing to miss. The listing states one fan.

On a dual-fan card, replacing only one side often leaves an audible difference in tone between old and new. If one bearing has failed, the other has the same hours on it — replacing both is the safer call.

Also, matching pin count does not mean matching wiring. GPU fan headers sometimes order their conductors differently from standard PWM case fans, and a reversed connector can leave the fan dead or damage the board.

Photograph the original cable's wire-color order and connector keying before you unplug anything.

Cards from other vendors — ASRock, SAPPHIRE, XFX, ASUS — are not supported. Even at a similar diameter, the screw pitch and shroud seat differ, so the fan either will not mount or the blades will contact the heatsink.

Product Info

The source listing is Amazon.co.jp (ASIN: B0C1KFCVGB), sold and shipped by a marketplace seller.

Seven specs are published: brand Rakstore, 85mm diameter, 4-pin header, 12V, forced-air cooling, one fan, metal material. RPM, airflow, noise rating, bearing type, and cable length are absent, and this article does not invent them.

On price: the captured figure was an order of magnitude out of line with what a single 85mm service fan normally costs, so no amount is quoted here. Prices for parts like this swing widely by seller and stock, and a captured value is not a current one.

Check the product page for today's price and compare it against other listings of the same part number. There is a hard break-even here — once the fan costs more than a used card, the repair stops making sense.

The rating stood at 4.8 out of 5 stars (96%) as of June 2026, but from only 6 reviews.

That sample size supports almost no conclusion about defect rates or longevity. Read the review text for someone confirming a fit on your exact card rather than trusting the star average.

Installation Pitfalls

The job needs a precision Phillips driver and, on some cards, a Torx driver (T5–T8). The sequence is: remove the card, remove backplate and shroud screws, unplug the fan connector, swap the fan, reassemble in reverse.

The common accident is the shroud: fan cables are often short, and lifting the shroud briskly can tear the connector off the board. Once every screw is out, raise it a few millimeters and trace the cable routing first.

If you separate the heatsink from the GPU, you are now committed to reapplying thermal paste and checking the VRAM and VRM thermal pads. A fan-only swap usually avoids this, but have paste and same-thickness pads on hand before you start rather than discovering the need mid-job.

Best Use Cases

• Owners of a PowerColor RX 6600 / 6600 XT Fighter with a noisy or dead fan. Far cheaper than a new card, with GPU performance unchanged.
• Anyone refurbishing a used RX 6600 Fighter. The fan is the most worn component on a used card.
• DIY users comfortable with disassembly who already own drivers and thermal paste. As GPU teardowns go, this one is easy.
• People stocking a spare. Service parts get harder to source as a generation ages, so buying while supply exists is reasonable.

Things to Consider

This is not an OEM part. RPM, noise, and bearing life may differ from the original, and you may end up with a different tone or fan curve response even after a successful swap.

If exact parity matters, ask PowerColor support about an official service part — slower and more expensive, but authentic.

Pin assignment is your responsibility to verify. Same pin count, different wiring order means it will not work.

Photograph the original, check continuity, and watch the fan spin with the case open on first boot.

Warranty matters. Removing screws or breaking seals can void coverage.

If the card is still in warranty, contact the official repair channel first.

Model mix-ups are the most common failure. Red Devil is excluded, and other vendors' RX 6600 cards are excluded.

Confirm the Fighter branding on the shroud and measure the fan frame at 85mm before ordering.

Treat the listing data itself with some skepticism. Marketplace pages sometimes carry wrong prices, part numbers, or compatibility claims.

The displayed price here diverged sharply from the norm for a replacement fan, which is why no figure appears above. Check that the page's photos, title, and stated compatibility agree with each other before you buy.

Who should skip it: anyone uneasy about disassembly, anyone still under warranty, and anyone hoping to improve cooling. For that last group, better case airflow or fresh paste and pads will do more than a new fan.

FAQ

Q. The Fighter is dual-fan — is one enough? A.

The listing specifies one fan. Buy two to replace both; a single new fan can sound noticeably different from the surviving old one.

Q. Will it fit the RX 6600 XT Red Devil?
A. No. The compatibility notes exclude it outright; the cooler design is entirely different.

Q. Can I use it on a SAPPHIRE or ASRock RX 6600?
A. No. Screw positions and shroud geometry differ even at a similar diameter.

Q. What tools do I need? A.

A precision Phillips driver, possibly a Torx driver, plus thermal paste and pads if you remove the heatsink.

Q. Is the 4.8 rating trustworthy? A.

It was 4.8 (96%) as of June 2026, but from 6 reviews.

Treat it as anecdote and look for a fitment report on your exact card.

Q. Will temperatures drop after the swap? A.

Only back to stock behavior. This part restores cooling; it does not exceed the original design.
