Announcements of new high-performance air CPU coolers tend to get rare these days. On the one hand, many enthusiasts switched to closed loop liquid coolers in the recent years, which is why the market of high-end air coolers shrank. On the other hand, existing models of ‘mega coolers’ are powerful enough for the vast majority of CPUs. Nonetheless, makers known primarily for oversized air coolers continue to perfect their offerings. This week Thermalright introduced its Silver Arrow IB-E Extreme Rev. B giant air cooler that can dissipate up to 320 W of heat.

The Thermalright Silver Arrow IB-E Extreme Rev. B is a giant symmetric twin-tower cooler made of aluminum with a nickel-plated copper base, 2×45 aluminum fins as well as eight U-shaped 6-mm nickel-plated heat pipes. The heatsink measures 155×103×163 mm and weighs 850 grams (100 grams more than the original one). When equipped with two Thermalright’s 140-mm TY-143 PWM fans that spin at up to 2,500 RPM to create a 130 CFM air flow, the weight of the cooling system increases to 1170 grams. Given such weight, the company supplies custom retention plates with the device. (Ian: It still doesn't come close to my 2 kg Thermalright TRUE Copper heatsinks! :D)

The manufacturer claims that the Silver Arrow IB-E Extreme Rev. B has a 44 mm clearance between the base and the fins, which maximizes compatibility with memory modules. Speaking of compatibility, it is necessary to note that the cooler comes with retention plates for AMD’s AM4 as well as Intel’s LGA 775/115x/1366/2011-3/2066 sockets. Essentially, the new version has gained support for HEDT processors that come in Intel’s LGA2066 packaging, something that the previous-gen Silver Arrow IB-E Extreme cooler lacked.

As Thermalright positions its products primarily for performance-minded enthusiasts and overclockers generally not interested in 'extreme' modding, the Silver Arrow IB-E Extreme Rev. B does not feature any RGB lights. It still looks pretty cool with an orange fan.

    Thermalright Ultra 120 from 2007 still going strong. (30/60 idle/load)

    On a core2duo?

    8700k. Just had to get their $15 adapter kit so it would fit on everything after socket 775.

    Yeah! I’ve got mine on a 1700X! Same $15 bracket on the Crosshair VI that has the AM3 holes on it!

    i bought 2 Noctua NH-D15's, contacted Noctua about the socket 1366 mounting brackets.. and they sent me both, no charge :-) works much better then the stock, and same Ultra 120 i had on the 2 1366 cpu's... the Ultra 120 is no slouch after all these years though.... also used one to cool my Athlon 64 FX60

    Got an adapter for the original big boy dual tower, IFX14 for my Ryzen 7 1700. Hits 4GHz and nothing can get it over 75C. The mount only fits horizontally, not optimal, but destroys all the $50 and under range coolers iv'e tried.

    Yeah, glad to see Thermalright going strong. I still have their XP-90 (1st heatpipe), and their older all copper unit which was like 10 degrees cooler than the all copper fin thermaltake it replaced. After upgrading to the D14, I basically couldn't upgrade again. Wonder how this revision will compare to the d15. More heatpipes, but the fin area...

    Still got one of them on a 2500k, still works fine.

    only thing that can stop working is that fan. 12 years is already a lot for it.
    other than that metal is metal, simple heat capacity of that 0.5 KG of aluminum does the magic.
    12 years of difference is ~10% of aerodynamics improvements & fan electrical efficiency. Nothing else.

    Same! On a 4790k here! Cooler started on an AMD X4 for me, then X6, then i7. Had to also buy the bracket. Great cooler.
