Lubrifying linear bearings for long-term use in an enclosure at higher temperatures (38C)

I run a lot of ASA prints in an enclosure (Lack enclosure). I measured the temperature inside the enclosure during prints and it reaches around 38C. My stock fan shroud started sagging so I printed a replacement out of ASA. This got me thinking: Should I use a different grease for lubrifying the linear bearings? The default grease seems fairly thin (liquidy) at room temperature, so I'm wondering if it gets too thin around 38C, reducing its longevity because of it running off the bearing surfaces prematurely. Is there a recommended alternative bearing grease for long-term printing with materials like ASA and polycarbonate in an enclosure?

I have used liquid Superlube.  No special lubricant.
