ASUS Unveils GeForce GTX 1660 Ti EVO Series Graphics Cards
ASUS today unveiled the Dual GeForce GTX 1660 Ti EVO series graphics card, which comes in three variants, a base model, a moderately overclocked A6G model, and the fastest O6G overclocked variant. All three stick to a common board design, which involves a 24.2 cm-long and 13 cm-tall PCB, and a 3-slot thick custom-design cooler. This cooler features a DirectCU II heatsink ventilated by a pair of 80 mm Axial Tech fans. These fans feature barrier rings that run along the periphery of the impeller to prevent lateral airflow, guiding all of it axially (downwards onto the heatsink). The cooler features idle fan-stop.
The cooling solution uses a pair of nickel-plated copper heat pipes that make direct contact with the "TU116" ASIC, conveying heat to the edges of the aluminium fin-stack. The shroud features a tiny RGB LED diffuser. A metal back-plate is included. The card draws power from a single 8-pin PCIe power connector. Display outputs include two HDMI 2.0b, and one each of DisplayPort 1.4 and dual-link DVI-D. The base variant comes with NVIDIA-reference clock speeds of 1500 MHz core and 1770 MHz GPU Boost. The A6G variant has a negligibly increased GPU Boost frequency of 1785 MHz. The O6G variant leads this pack at 1845 MHz. The memory remains untouched at 12 Gbps on all three variants. The company didn't reveal pricing.

Still the other cards in their GTX 1660 line up have terrible cooling and are effectively thermal throttling, which is quite sad to be honest... not really that quality we know and love ASUS for.
Single fan vs dual fan cooling solution - 2-3'c difference. though the EVGA reviewed has lower idle temps because the fan doesnt stop like the MSI.
Heres another example. The Strix OC version with triple fan config - this is a bigger improvement over all.
DUAL and TUF are simply terrible especially considering their price, as for the same money I could get an MSI Armor OC with decent size heatsink with heatpipe and two large fans and a backplate... or better yet for a grand total of €6 more opt for a Gaming X, which is still €30 cheaper compared to a STRIX model that actually has decent cooling.Not really a fan or the amount of fans... in this case its the amount of heatsink (or lack there of) is the issue, just look at this... I mean you can see the PCB directly under the fans. :(
GPU Temperature Comparison / Idle Load Gaming Noise
ASUS GTX 1660 Ti STRIX 33°C 58°C 32 dBA
ASUS GTX 1660 Ti STRIX (quiet BIOS) 45°C 65°C 29 dBA
EVGA GTX 1660 Ti XC Black 33°C 69°C 38 dBA
MSI GTX 1660 Ti Gaming X 50°C 67°C 32 dBA
MSI GTX 1660 Ti Ventus 32°C 68°C 35 dBA
Zotac GTX 1660 Ti 36°C 74°C 30 dBA
With OC included, it typically adds just 0 - 1C. I have never heard of throttling occuring anywhere those temps except in cases with inadequate case cooling.
