Thermalright SI-128?

[Praxis1452]

Maybe I'm wrong but I thought that the wavey fin design helped air for some reason... I'm not exactly sure why but I'm almost positive I read on xbitlabs? I forget where that it helps... Anway larger heatpipes aren't better in my opinion. Having a bunch of smaller heat pipes gives more surface area than having large ones. The center of the heatpipe is still warmer when the outside is dissipating it's heat to the cooled area. The SL-128 looks to have a pretty complicated mouting to me... but I don't install heatsinks that much either. How was the other one mounted?

Praxis, Google volume of a cylinder and do the math.

6mm diameter X 240mm long=6782 sq.mm, now, times 5 pipes=33910 cubic mm

8mm diameter X 240mm long=12058 sq.mm, now times 4 pipes=48232 cubic mm

That figures to about 42% more volume for the good juice and wicking material for 4-8mm pipes vs 5-6mm pipes. Now consider the area of copper pipe in contact with the aluminum fins. These are nickle flashed then soldered together.

I am talking SI-120 vs SI-128. 1000g uber towers can take a hike in my book. For some reason I just don't care for heat pipes that are U' bent, like on the Ninjas. They work well and guys do like'em..that's good enough.

The wave desing on the fins was for looks as far as I can tell, theres no way it could help cooling. Galvanized; well put.

Anyways, as soon as someone finds this for sale, let me know. I want one, and SOON.

I guess this says it all...

Source: Thermalright SI-128 - Press Release

We?ve widened it, heightened it, beefed up the heatpipes, and put lots more fins in it!!

The end result? It?s bigger, it?s ?badder?, and it?s got more cooling power...

Thermalright?s SI-128 [is] the Goliath version of the SI-120! Need we say more?

Heh! You know what? The closer I look at this thing, I more I like it!

If you'll pardon the pun, I'm starting to warm up to the idea...

This is a 'good thing', right?

Not trolling... just making sure we're on the same page...

The SI-128 would appear to be the *new* king of standard radiator layouts for Intel LGA775 users, and a worthy alternative to the Ultra-120 and/or SI-120 in the AMD community!

 

[skooma]

From "another winner" to :new king......" This thing is getting better all the time

Anyway, I agree, this thing looks sweet. I like my xp-90 but i'll gladly take a step up to this "king" provided svc runs a deal on it :laugh:

 

[VinDSL]

LoL!! Busted!

I'm trying to talk 'myself' out of waiting weeks or months for Tuniq a.k.a. Sunbeamtech to get their act together...

With that in mind, the SI-128 is starting to look more n' more compelling -- even regal! :laugh:

 

[skooma]

you think we aren't watching :laugh:

I'm not a fan of the towers myself.

did i miss it or is there no price right now?

Heh! Do you mean 'no price' for editing my posts, or 'no price' for the coolers?

If you're talking coolers...

My Tuniq T-120 was $48 (back-ordered) + shipping

The SI-128 is $44 (in stock) + fan + shipping

If you're talking editing...

You tell me...

I wasn't actually comparing the SL-120vSL-128...

The thing is that Surface area is better with smaller pipes but you have to use more of them... I was saying that I thought it'd be better to use smaller heatpipes but many more of them.

So what are you looking for then? How many pipes do you think they can fit and how will it make it better?

As a side note, your sig is longer than your post, and seems to be meant to ignite flame wars. :thumbsdown:

I have an XP-90 and 90Cu. The XPs block air to the RAM and VRM/caps by having fins to the base. The SIs do not. They get air to the RAM and the important area between the I/O plate and CPU...That's the way I see it.


...Galvanized

Makes sense, hadn't thought about it that way... I'll definitely have to check it out for my next build, though I'll wait and see a few reviews/comparisons of it first. Thanks Galvanized.

If I understand correctly, you're asking if the SI-128 is an example of a good hsf that blows air onto the motherboard. If that's the case, than yes. Looks like the same basic design of the XP-120 (loved mine while I had it, kept the PWM mosfets and ram very cool). In my experience the towers work very well too, they just don't cool the board components as well.

 

[Remedy]

My only beef with the SI-128 is the price. I can get an SI-120 for $31 instead of the $47+ for the SI-128. That's almost a 40% increase in price for less than 10% increase in performance of the 128.

I think I may just go ahead and get a SI-120 for $31 with a nice Delta Tri-blade 120mm.

My sig is my sig and I don't give a fvck what you think. I don't even care if it wasn't wreckage. I just found it quite funny. It wasn't meant to be personal either. Just how pathetic the video forum has become if you want to think of it like that.:| Also my sig isn't that long. It's only 2 quotes. Contact the moderator if you don't like it. So everytime I post I gotta make a post longer than my sig? maybe I should quote my sig and then write a sentence then post. :roll:

ACtually I thought they should use 8... Because they heat also gets spread more evenly or you could pack more into the sides. I mean look at the Zalman 9500. The heatpipes are at the bottom not the top. I think that if the heatpipes were spead through the middle of the fins it'd help the cooling ability. With 4 large heatpipes some areas of the fins are cooler while others are still warm.

Its intersting how people actually have come to expect these companies not make any money!
People think prices should be adjusted to account for the poorest consumer.
Not realizing that if money is an object.
Just don`t buy it.
Sheese quit crying. Buy something else.

After reading a couple reviews that pitted the tower-style hsfs against the squatter-style hsfs (XP-120, SI-120, etc.) it's pretty conclusive that the squatter-style cool the board better. It seems intuitive that air should be directed through the case as efficiently as possible but if the mosfets on the PWM area don't get cooled (along with ram and other board components) than overclocking will suffer. There were a couple threads in the CPU section where testing had shown that PWM temps affected ocing ability more than you'd think. I guess what I'm trying to say is that having air blow down on your board is a good thing, even if it doesn't route the air through the case as efficiently as possible.

Thats not true at all.
For the very few tower heatsinks on the market. The Scythe Ninja in review after review gets better marks than any of the "squatter" heat sinks. Albeit the margin is only 1c-3c at best!

The Artic Freezer 64Pro also is right up there along with the Tuniq heatsink and the Zalman 9500!

If you have peoper airflow in your case to begin with having airblowing down on your mobo is negligible at best!

Have fun!

Please do report it Remedy. You have been a VG contributing member in this forum, never nasty and always willing to help when you can.

I quote this post because I will be sending a PM to the Mod *shrugs*. It's sad that a 50 year old man can act as JY does, pathetic really. One of the Mods over at badcaps.net asked him if he was just a troll. This guy makes friends where ever he goes *sarchasm*


On Topic, Thanks for the post. I ordered one via Froogle along with a Scythe S-Flex fan. Now all three sinks here get pushed back The Zalman 7000 ends up in the used parts box.


...Galvanized

 

[Remedy]

You ordered a SI-128 or 120?

 

[GalvanizedYankee]

A 128. It will push a XP-90C where a XP-90 is and the XP-90 will bump the Zalman 7000 into the used parts box.

I like sinks that are not locked into one type of chip. That has it's advantages.

I went with a Scythe S-Flex 120x25, 1600rpm @ 63.7cfm. This sink may only need 40cfm but fans can always be undervolted

Nice job noobster, your reply to my "side note" is yet again longer than your "contribution" to the thread. :laugh:

Anyway, just packing more pipes in doesn't mean its going to cool any better. By adding more pipes, they'd have to be more narrow, no? You're adding surface area but losing the cooling that the volume of air in the pipes gives.

And if you're thinking you can just slap staggered pipes throughout the cooler, there is such a thing as manufacturing costs to consider

They add ~50% more fins and increase the volume of the pipes by ~50% of an already very good cooler.

 

[Remedy]

Didn't you purchase a Delta Tri-blade 120mm low output before?

Yes Sir, I did. It does quite well as a case exhaust fan and would work well on the SI-120 sink's fin spacing. The 120's fins are not widely spaced, as on some towers, but are not as tight as the 128's fins. I chose a 7 bladed fan because I think it will drive better mm of h2o at low rpm vs a triple bladed fan and drive air better through the very tight fin spacing of the 128. Now cleaning dust out of the 128 may not be as easy as the 120. Just can't win.

I have two NMB 120x25 w/hub mounted thermistor that peak at 116cfm but rather than play with under volting one of those, I thought the ceramic bearinged fan should get a shot.
