ATENTIE la padurile PTM7950 made in USA, pentru ca padul nu este fabricat in state. Astea se gasesc pe aliexpress si sunt numai fake-uri !

Unul dintre cumparatori a tinut sa faca si un scurt review, ii multumesc cu aceasta ocazie pentru linkul din clip ! www.youtube.com/watch?v=4MjreNCk3Ws

40x40mm sau 80x20mm 60 ron
80x40mm sau 160x20mm 120 ron
20x40mm 40 ron

Prima poza este cu produsul original vs fake, iar ultima poza este cu una fake de vanzare, de pe emag sau aliexpress este acelasi lucru, macar astia de pe emag au scris ca este pasta similara in titlu

ATENTIE LA FAKE-URI. Padul este ORIGINAL 100% PTM 7950, este exact aceeasi pasta care se vinde si pe www.moddiy.com/products/Honeywell-PTM7950-SP-Super-Highly-Thermally-Conductive-PCM-Pad.html
Cea fake scade temperatura cu aprox 4 grade (dar in maxim 2 luni trebuie schimbata iar), originala cu peste 8 grade si rezista ani de zile.

Iar vis a vis de fake-uri, dupa cum si producatorul spune pe pagina lor principala:

Be caution! We have noticed that there are many places selling fake, mixed, or expired PTM7950.

Some of them are simply fake which it is not PTM at all.
Some of them are selling PTM3180 as PTM7950.
Some of them are mixed with other thermal paste.
Some of them are expired PTM7950 which shouldn't even be sold.
Some of them are selling 0.2mm thickness as 0.25mm (the optimal thickness for best performance).

Unfortunately, it is really hard for users to distinguish them. You will still see thermal improvements initially by comparing with a dry out paste. But the thermal performance will be extremely downgraded after a period of time if comparing it to the original new PTM7950.

Product Description

Honeywell PTM7950 Phase Change Thermal Pad is the best-performing thermal material in the world, based on our in-house testing. It works perfectly for CPUs and GPUs.
PTM7950 is designed especially for high-performance chips requiring exceptional thermal performance, durability, and reliability. Nvidia and Lenovo have already been using PTM7950 for their top-of-the-line flagship GPUs and gaming laptops.
Honeywell’s PTM7950 series, a super highly thermally conductive Phase Change Material (PCM) in both pad and paste formats, is designed to minimize thermal resistance at interfaces, maintain excellent performance through reliability testing, and provide scalable application at a competitive cost.
Based on a novel polymer PCM system, this material exhibits excellent interface wettability during typical operating temperature ranges, resulting in extremely low surface contact resistance.
A proprietary material provides superior reliability (pass 150˚C baking 1000 hours, T/C-B 1000 cycles) and maintains low thermal impedance (0.04˚Ccm2/W no shim), making the PTM7950 series desirable for high performance integrated circuit devices.
