High performance memory kit for a fanless mini-itx home server based on a i9-10900T and a Gigabyte Z490I AORUS ULTRA?

I am looking forward to build a fanless mini-ITX computer (with a dedicated computer case). The criteria that are important to me for this platform are the following:

1. Reliability: no system crash, no instability
2. Durability: long-term system stability (think of a home server running 24/7
   for years)
3. Performance: as high as possible given the energy constraints and that 1. and 2. are met

The rest of the platform will be:

• CPU: Intel Core i9-10900T: 10 cores, 1.90 GhZ (4.60 GhZ Turbo), 35W TDP (as this processor can go up to 120W TDP when no limitation are put in place, I will put a TDP limit in the bios given that the platform will be fanless)
• Motherboard: Gigabyte Mini-ITX Z490I AORUS ULTRA (rev. 1.x), manual here, official memory support list here

Given my criteria and my CPU and motherboard, I would like to know what would be the best memory that would fit my needs given the following constraints:

• Type: DDR4 DIMM (non-ECC)
• Amount: 64 GB (2×32 GB kit)
• LED: for equivalent kits performance-wise, without LEDs will be prefered
• Voltage: for equivalent kits performance-wise, the lower the better
• Brand: preferably one known for reliability, stability, and durability
• Max price: irrelevant in the limit of about 500 euros/dollars for the kit

Since I am looking for something extremely stable, I am unlikely to tweak a million options in the BIOS. Overclocking will not be a thing, since it will be for something that will be used as a fanless home server most of the time. But even with these constraints, I am looking for the best possible performance.

Any advice? I am looking for 2 or 3 good options that would fit my needs.
