Accelero S1 killer ?

I say the Accelero S1 is toast if that performs as good as it looks. I bet it going be more expensive by wide margin but knowing Thermalright's repuation for build quality it would be worth every penny. I buy one and ditch my Accelero S1.

Fins are packed much closer than on Accelero and they are also parallel to the rear expansion slot covers which means that you won't be able to dissipate heat using negative pressure with expansion slot covers off or by using fan on the upper P182 HDD section.

I suspect this will make a great performing cooler, provided it is actively cooled, and will make a great choice for HTPC cases, many of which won't fit Accelero S1, however I believe it will be hard to use passively and Accelero S1 will hold the edge in passive or very low airflow configuration.

I'm thinking it won't cool as well as an Accelero S1. The heatsink is more compact, being both narrower and thinner. The fins appear to be spaced closer together, and face perpendicular to the path of airflow, so it probably won't perform anywhere near as well when used passively. On the plus side, it should definitely fit into smaller cases.

Edit: Wow... I was a few minutes late and Jazz covered everything I was writing in my own post. : P

SLI users rejoice! If it is as good passive as the S1 (probably wont match it, but could come close) then this could win over the HTPC and SLI market, something which is rare indeed!

I don't think Thermalright aim is for the passive market they have never wide spaced fins. I'm not to high on running anything passive I perfer low noise, low RPM fan. Some airflow is better then none. I think this way the can cater to the performance overlocker crowd and the silent PC crowd.

Assuming both heatsinks are using 2 of the same fans, I think performance difference will be within 5C. However, there's no way Thermalright can get that thing under $40. AC S1 will still maintain the best value, me thinks.

This one clearly wins on size. In addition to SLI setups, it will fit some HTPC cases the Accelero won't.

Thermalwrong just seems to not have a clue as to how actual cooling works. It looks fancy and good, but it'll be like their CPU coolers. Should work better than a Ninja... but only with loud fans, which aren't much quieter than the stock vacuum cleaners.

Really? i suppose SPCR is pretty poor at reviews, since they found that using the exact same reference fan on the TRUE it bested every other cooler at 12 or 9v, and was within 2c at 5v (490rpm) to the very best passive specialised heatsinks. Id say that they are doing at least something right there.

The problem was that it wasn't any better at extremely quit speeds, despite all of the extra metal and cost. I don't expect this to work as well, especially passively, as the S1.

Thermalright is more reputed for OC cooling, and to have the first place in perfomance even being pricey...
The fact is they lost that edge in VGA cooling (and direct touch heatpipe), until maybe a review of the T-Rad. ^^'

A Thermalright engineer at Computex 2008 told me that TR is eyeing the quiet/silent PC market and welcomes inputs (from quiet/silent PC fans).

If they wanted to really please the silent crowd they'd take their TRUE, or this GPU cooler and take out 1/3 of the fins and then space out the remaining ones. Much less restricted airflow, cheaper and lighter. A pattern we're seeing with them right now is cram as many heatpipes and fins as possible onto the heatsink. This may look nice and cool well when you have a 2000rpm 120mm fan on it, but for passive cooling and acoustics its very bad.

jmke · Post by **jmke** » Sat Jun 07, 2008 7:58 am

this GPU cooler is based on forced aircooling, you'll have to fit a fan on there to make it work, passively it will turn out less impressive then the picture may lead you to expect.

From Thermalright support, it should be available in late-august. ^^

I can't understand what they were thinking with this design.

As has already been pointed out, the fins run the wrong way. It would be better to make a dual slot cooler with find parallel to the card, so that air can flow out the back of the case. Also, in a case with front fan blowing on to the graphics card, you can make better use of that with parallel fins.

Also, why no pads for memory? Maybe they are going for universal GPU compatibility, but that leaves you with using those naff stick on heatsinks for RAM.

Why only one 120mm fan? Larger cards have room for two.

I'd like to see something with parallel fins and both top and bottom fins (like the old Zalman coolers) since many cases have an open slot above the graphics card as well.

I expect it will perform very well, but it's going to have to be very cheap to compete with the Acceleros.

Release date should be late July ... see http://www.overclock.net/4037895-post71.html

hmm...the sideways orientation of the fins might actually be a good thing - many cases (esp. Lian Li) have a 12cm sidefan duct. In such a setup it might be possible to cool this rerasonably well with just that - although, as others have already pointed out, I fear the fin spacing might be a bit too tight for that.
I'd also beat the huge space requirements of the S1/2...in my current setup card + S2 + 12cm fan takes up 3 1/2 slots and sideducting an S1/2 is also not feasible as it's far too wide and even if you'd bend it downwards it would obscure just as many extra slots as it is now...

Such a setup might be even more interesting for SLI fans - each card would only take up 2 slots and you might even be able to cool 2 or 3 cards with a single 12cm fan - just speculating here ofc, wether such a setup would actually work would have to be tested first

If I can get my hands on a resonably priced one of these I'll give the sideduct cooling a shot - single card only though, I don't have a sli capable setup.

I've been looking at gpu coolers for a few weeks and I was pretty excited about that thermalright hr-03 gt (for 9600gt) but this thing looks sweet.

I tried to find a review for it and found this thread... better than nothing I suppose!

I think I've seen that the T-Rad2 with 2 92mm fans performs slightly better than an Accelero S1 with Turbo Modules. Which, I think, translates to the Accelero S1 with 120mm fan (or 2 92mm fans) being better still, for less money.
