Under bonnet temperatures
Discussion
I have been using my Tuscan for commuting a bit recently, which involves at least thirty minutes in nose to tail traffic in the morning. Water temperature generally sits at 92-96 when hot, occasionally sneaking up to 97/98 indicated. Oil temperature generally sits in the low 90s. This is of course on a cold morning. During the summer on hot days, it also keeps similar temperatures - though I did wonder whether it was maybe a couple of degrees higher than it has been, as I can't recall often seeing 97/98 water temperatures before. From a bit of searching on here, it seems these are pretty typical temperatures for a Tuscan to run at and aren't something to worry about. It has never even hinted at overheating whilst I've had it.
As is common with Tuscans, it gets very hot in the cabin particularly during the summer (and I don't have air con). I have also noticed that the paint is starting to craze a little above on the bonnet above the exhaust manifolds - which is a shame, as it had a repaint a few years ago and was mint when I got it. I suspect the previous owner didn't have this problem as he didn't use it in traffic.
I wondered if there was any common wisdom about ways of reducing underbonnet temperatures? I know a decat is an option at least for in-cabin temperatures, though I want to avoid making the car unsociably loud. What about changing the fans to kick in earlier, or uprated radiators?
Or are the temperatures noted above fine and nothing to worry about?

Zircotec were a spin off company from United Kingdom Atomic Energy Authority (Harwell) , the coatings were developed for Nuclear reactors.
Cats & Manifolds were about £1000 in Sterling Silver , and another £500 to have them removed and refitted without dropping the engine

Thanks, I've dropped them a line for an estimate and also checking with my local specialist as to how much to remove and refit cats and manifolds. I've also asked the specialist about fitting heat shielding. Having one with and one without, save the DIY applied ceramic stuff you bake on in a domestic oven, no real difference so I reckon a waste of money. Did meet them at Autosport two years after it was done and told them so, it was peeling as well which indicated to me a lack of prep. Shame as it cost enough. pretty poor public schoolboy response as customer service, I told him what he could do with that as well. Anyway either wrap or DIY with a can and bake on, needs prep if you do which is painful and slow.
Try the low fan temp ECU from Dom and decat as well. The real damage is done when you switch off and heat soak occurs so best to keep temp down as much as possible.
