Thermaltake Silent Boost HSF $26.99 @ SVC

[Aardy]

On a stock 2600 with a Soyo Dragon Lite, my temps have dropped 10 degrees from stock HSF but it's still in the mid 40's range. Is htis a good range?

 

[Granorense]

As I said before, I am very pleased with this product. I returned my Aero7 wich I bought at retail price at Fry's for $39 and got this one for $10 less, this cooler is much better. It runs quiter and my 2600+ is about 4 degrees cooler.

Here is what I got:
Soyo Ultra Platinum KT400
Athlon 2600+ @2127 mhz (170 fbs for now)
ATI 9600 PRO
2 80GB WDs in a Raid 0, and a 40GB WD HD for Linux experiments!
Enermax 460 W with a 90m intake fan
5 80m fans
Case is a Full tower TurboLink
other irrelevant stuff.
Room Temperature is 82 (Its Arizona)
Case Tem is...(wow I better turn air conditioner on 36 deg)
my sensor on for cpu is 47
ThermalTake SilentBoost at 2650 rpms (silent)
Using Motherboard Monitor, sensor 3 doesn't work, it goes up and down like crazy.

All my funs are controlled by a Vantec Mexus and I have everything turn down to the lowest voltage. Even my PS is at the lowest.
I run Prime5 for abaut 5 hours, and temperature didn't go over 50 degrees.

I have to mentions that this HS is very eassy to install, and I like the desing of it too. I would like to install a grill on it thouhg but due to its round shape seems hard to do. (no time to modify any thing or interested on)

Wow that ducting mod looks pretty cool. Does anyone know if they have one that is not curved? I already have a hole cut out of the side of my case, right above one of the processors (it's a dual processor machine) and it would be cool to have a straight duct going right to the cpu.

 

[kellybrf]

no, they dont make a non-curved ducting mod as it would defeat the purpose of the mod (or at least diminish it.)

my temps keep dropping with this hsf, im down to 37

why would it diminish it? I'm pretty sure you are wrong here.

maybe this?

 

[kellybrf]

the curved design allows the air to fully hit the die by redirecting the air. a straight duct would still have a dead spot b/c the fan is blowing the air straight down

 

[GtPrOjEcTX]

yep, incorrect as I thought.

although true the tubing redirects are, so would a straight tube. given say 4-5" of length, the air moving straight does not move exactly straight, there are variations. ex. the air that will hit the sides of the straight tube would bounce off and fill the tube up.

the entire point of the tube is to get fresh air.

 

[kellybrf]

hence the diminish comment. if straight would be the same/better they wouldnt have made it curved

Here's an article on lapping.

Umm.. I don't get it? What's the piece of glass for and how do you "mount" the sandpaper to the glass? Does this guy mean to have the HS upside down on a table, then (somehow) attach sandpaper to a large piece of glass, then sand down the bottom of the HS as it lays flat on the table?? Any other links? Never really thought about lapping till now (bout to install some new shizzle).

 

[kellybrf]

you put the glass on a table, place the sandpaper on top of it and put some water on the sandpaper. then take the heatsink and move it around the sandpaper in a figure 8. shouldnt need to attach the sandpaper to the glass, but a little scotch tape wouldnt hurt

Ahh it's all coming into focus now, thank you, I had it backwards. Sorry for straying OT, but, and there's always a "but", isn't this really a two step process? First making the contact area of the HSF perfectly flat, and secondly polishing it up? Or is using metal polish not necessary? Judging by the link, it looked like it turned out pretty cool, though you'll never (hopefully) see that side of the HS again. Call me naive, but I'm surprised that they don't make them pre-"lapped" coming from the factory. You'd think that surface would be as flat as flat can be. I mean, if they could shave 2 degrees off those things by simply wet sanding/polishing them before selling them, I'm sure people wouldn't mind paying a few extra dollars for one that was lapped using state of the art methods etc. Wouldn't the HSF manufacturers want to do this simply because of marketing/advertising they'd be able to do..."Ours is lapped, ours is best, ours runs on avg. of 2c cooler!"? If you had a choice between a brand new "lapped" HSF vs. a new un-lapped HSF and the cost difference was let's say less than $10-$20 which would you choose? I'm just surprised that in this day and age, with manufacturing technology being what it is, that we as consumers have to break out sand paper to get our supposedly sophisticated and high-end computer components to work at their best. Like I said maybe I'm naive, maybe I'm missing something? I apologize if this post doesn't belong in this thread and for ranting, thinking out loud, or whatever it is that I'm doing

 

[s0ssos]

hey guys, so someone said this wasn't a good heatsink, but someone else said it was? what's the general consensus on this?

seems to work for most people... not for me though... don't know if it was my case configuration where it was right next to an exhausting fan but it was 5c hotter than my aeroflow so i returned it.

Thanks much, that's exactly what I need.

Well I got mine today and put it in. I was previously using a Volcano 9 and it was SO LOUD.

I put this one in and it's so quiet. I love it, but I am running about 3-5 degrees celcius hotter than the previous fan, but I think the silence is worth the 3-5 degrees.

I just got mine today too ~ I switched from a Volcano 9 (smart fan II) to this new one. Its a LOT quieter, and I went from 54C to 40C. Very happy.

54C to 40C?? is that idle or under load??

I'm still wondering if my 42C with this fan is good or not (stock fan was 55C)

they made it curved b/c 95% of all cases have some sort of ventilation at the rear of the case. Making it straight would assume that 95% of cases have a side ventilation whole.

Good

 

[vfrjim]

I installed it today in a new system that I was building, temp is sitting at 36C, not bad at all.

No. The mod you're referring to isn't intended for exhaust/intake purposes, it's specifically designed and marketed as a means of redirecting the air coming out of the fan mounted on an 80mm compatible heatsink. It's not even an actual duct, it's just a curved extension that focuses the moving air more directly on the center of the heatsink. A duct uses a much longer extension to bring cooler (at least, hopefully cooler) air directly to the heatsink, or actively direct hot air coming off the heatsink out of the case without recirculating it, and can be either straight or curved, depending on where the air is being brought from/sent to.

Have a look at this page, which includes a helpful diagram of how the mod helps redirect the airflow. As can be seen in the picture, and read in the explanation next to it, it has absolutely nothing to do with ventilation.

And as to the question of whether straight fan mods like this exist, FrozenCPU has both 80/92mm and 120mm versions. In regards to the airflow, it should actually improve it, since it's being directed instead of allowed to just blow in all available directions. It should also remove the dead center, as the cone of air moved would now be restricted to a tighter space, thus forced back into a controlled pattern.

I have one of the ThermalTake mods, but I never installed it because the clips on my SK-7 won't fit (the shape of the mod prevents the clips from settling into place). Instead, I just opted for volume over finesse. 7 80mm intake fans (4 in front, 3 in side) and a single 80mm exhaust, all quiet enough to satisfy me (i have to actively think about the sound of the fans in order to actually hear them, as the TV tuner card on low volume all but drowns them out), and a couple of open PCI slot covers, provide more than sufficient airflow to keep my CPU and vid card highly overclocked and cool enough to have a little more headroom.

54C to 40C?? is that idle or under load??

Those were bios idle temps. I've got a 2400 overclocked to 1.7 w/ 333 bus

I am not getting how you guys can get it so low. Mine goes into the low fifties when really under load and I already have Vantec's iceberg blue on one of my RAM, a HDD cooler, Artic Silver 3 in my 2600 (no o/c) in an Antec LanBoy. Oh, case temps go up to 40 when under load too. Is that bad?

 

[Su1c1da1]

different mobos read temps differently, but my question is do you guys leave it stock or do you lap it with those temps?

I think somewhere, something got messed up. i was talking about this
