Thermalright SI-120

Post by ChrisH » Wed Aug 24, 2005 9:18 am

I had no idea this was on the drawing board. It looks like it can cool as well as the XP-120, but is compatible with all Intel P4 and AMD K8 motherboards. It is slightly cheaper and is for sale at the Heatsink Factory.

Actualy, from the review I saw it can cool better than an XP-120 when you are using low speed fans.

Cut the thin metal support and layer four of them together. Now you've got yourself a passive CPU cooler for Athlon64.

That wouldn't work very well. The fin spacing is too tight and the fins face the wrong directon on most motherboars. Not to mention it wouldd cost 200.00. You can et a ninja for 45.00, so really I don't see the point.

You can bend the heatpipes! I'm sure you can pick them up for $20 each.

What does bending the heatpipes have a nything to do with it? The SI-120 costs 45.00, those 4 of them would cost almost 200.00 after you add in shipping. In the endit would not work passivly for the reasons I outlined above.

There's a gigabyte cooler that's similar

Gigabyte make a cooler kind of like this, with a gap between the hotplate and the fins. It's supposed to reduce the resistance the fan sees dramatically, because the air blows straight through the fins - so it makes sense that this is recommended for low-speed/low-noise (hence low-pressure) fans. The Gigabyte cooler works quite well, but I think I'd prefer this one (I like Thermalright's quality).


I had some major issues putting the last screw in to hold a motherboard into a case when using an XP120 - the screw (the one behind the keyboard socket) was next to impossible to reach with the XP120 mounted. In the end I removed the top fan (I was installing in a P180 - thank goodness!) and then it was simple enough. I suspect it would have been a little easier with this heatsink, but I think I might still need to remove the fan :) (I put the XP120 on before mounting the motherboard because I thought it would be easier that way - it was easier, for the first 8 screws :D )

It's actually bigger and heavier, no wonder if it cools better! It fits more mobos since the fins are placed higher up from the socket.
The slightly lower price is probably because the fins are not welded to the base which should give lower manufacturing costs. 30 g extra metal won't make any difference.

XP-120: L110 x W125 x H63 (mm), 370 g
SI-120: L140 x W120 x H88 (mm), 400 g

Edit: Dunno about that 88 mm height, that's exactly 25 mm higher... Maybe measured with a fan attached?:?

As with the XP120 paperweight I already have it still will not fit any of my mobo case combinations - so I will have to stay with my XP-90c.
Nice try - but misses the mark for me !
Psu clearance in a Sonata Case being the main issue and the Micro ATX InWin cases I use are even more cramped so, just not an option - for me

Any idea if an SI-120 will fit on an ASUS A8N-SLI premium in an Antec Sonata II case?
