I'm a Spanish speaker and it doesn't sound funny to me. Slight differences in your native language are very distinctive, so I don't read "Culito" when I see it. Do you think Apple computers is too close to Asshole?
Everybody is different, but the 33800 laugh reaction in the Facebook post https://m.facebook.com/NVIDIADataCenter/photos/a.33432954734... (versus just 811 likes, 180 love, 115 surprise, 104 care and 14 sad reactions) suggests that most Spanish speakers read without the H.
You can’t really say it with the “h”. Spanish has nothing corresponding to the English “h” sound, and the overwhelming majority of Spanish speakers speak dialects with nothing like the English “th” sound either (the ones that do have it spell it “c” or “z”, not “th”).
I'm a non-native intermediate Spanish speaker and it was my first thought. However I think it's cute and it makes people talk about it, so it's not a bad name.
