I used a Silvretta with a G3258 ( 65w TDP) and mostly fine except under sustained heavy load, bearing in mind that there was no added air movement from case fans etc. not a restrictive case, and with ample room around the CPU and cooler.
It was noted on an earlier thread about the Silvretta that the finish to the base was fairly rough and unfinished and this may have contributed to a poor thermal bond and lowered performance. The cooler itself is rated to 95W Intel and AMD, but manufacturers figures are usually over optimistic for real world applications, so probably less than that, but if finished properly, who knows??
The cooler is replaced for now with one I made up from parts, which works better and is practically silent, giving me an opportunity to "improve" the SIlvretta..........First thing is that poor base finish...........My method is a piece of machined granite perfectly flat and inflexible, as a work surface, then grades of abrasive paper...........starting at 1000 grit and progressively 1200, 1500, 200, 2500, all lubed with light machine oil.
It is obviously important to keep the base dead flat, any tipping and rounding will be very detrimental.
For the fan, before trying any replacement I will be peeling the label back and trying a drop of oil........( it was starting to be audible)
But I will probably find a replacement fan with more effectiveness eventually.
The Silvretta is just one of many coolers of this pattern, the more expensive of which will already be finished to a higher standard, but essentially the same unit.
