AC Accelero S1 is the BEST cooler for 8800GT / ATI38?0 cards

yamahaSHO · Post by **yamahaSHO** » Fri Dec 14, 2007 9:34 am

djkest is correct, they are Yate Loon fans. Price/performance wise, I think they are the best. From where I sit on the couch, I cannot hear my computer with the fans turned all the way down.

The Accelero S1 has officially floored me. I just slapped it onto my Sapphire HD3850 without a fan, thinking I would see how it would perform and then add an appropriate fan after the fact. FYI, my system is inaudible from 2 feet away (except for the hard drives).

I'm half an hour into ATITool's artifact tester... and the temperature has stabilized at 57C. It's 25-30C better than the stock fan @ 70% speed, which was very loud by my standards.

Don't even think about, just buy it. It's $20 US/CDN at NCIX right now.

Now if only I could overclock this thing... Overdrive is greyed out and when I raise the core speed by even 1Mhz in ATITool, it crashes my system.

Ok, finally finished installing the Accelero!
It took me a long time as it wouldnt fit in my case because my 3D Mercury case has built in water cooling and the pre installed gear was in the way preventing the accelero from fitting. I had to remove 4 fins plus both plastic black covers to make it fit ( In needed to remove the black plastic cover next to the sata connectors of my DFI NF4 ultra d as it wouldnt allow me to use on the satas!
Well, even without 4 fins my load temps are 49C compared to my 63C with the stock cooler....the catch is, to get 63C with the stock cooler I was running at 100% fan and getting cold air from the window using an air duct (temp outside at about 30F when I tested the last time).
With the Accelero I am getting 49C load with a room temp of 61F...if I were to use the air duct it would be much lower.
Also, while overclocking higher wasnt my main concern I was able to go from 753/1836 to 771/1890 with a much more silent setup.....THUMBS UP!!!!

ATItool is not compatible with the HD 38xx cards. It can't OC the cards. There are a couple programs that can though. I was able to overclock in Catalyst Control Center, and thats what I currently use because heck, it's going to load anyway. You have to enable overclocking by clicking a certain button, can't remember what it is off the top of my head.

You can also overclock your card with Riva Tuner by clicking on the little triangle to the right of your video card, then clicking on the icon that looks like a PCB.

Has anyone managed to use the S1 with Crossfire or SLI? Surely its possible with a bit of modifcation.

Hopefully the S1 will fit in the upcoming Fusion Max

How many MM / INCHES above the PCI-E slot screw point does the S1 extend?

It works with SLI. You just need a flexible SLI bridge

I just posted my opinion of the S1 for the HD3850 in my silencing journal thread @ viewtopic.php?p=384805

Here is the snippet for the HD3850:

AC Accelero S1 - Well, the voltage regulator heatsink did NOT match the HD3850 so you HAVE BEEN WARNED. I took out my cheap dremel-wannabe tool and cut off the voltage regulator heatsink section from the original cooling of the card. I also had to shave done the screw mounts because the heatsink was not making contact with the regulators (good thing I checked). Fits the card great and mounts without problems with the S1. I have my gripes with the S1. The main issue is the absolute cheap feel of the whole package. The aluminium fins are easily bendable and were actually slightly deformed where the plastic casing of the S1 was placed. After a bit of bending everything was aesthetically pleasing. The ram heatsinks are very crappy. The "thermal glue" on the back of them doesn't stick to ram to say the least, but it was also irremovable from the heatsink itself! I ended up leaving the glue on it "as-is" and just applying MX-2 on the ram along with 4 drops of superglue on each corner. I think that will work ok, as I tried to pick up the GFX card with each one of the heatsinks and it held up ok Smile Mounting the S1 itself was a bit tedious, due to adding the extra support clips (didn't go as smooth as it should) but in the end - this is the best mod done so far! Temps dropped from 90c at full load to 58c passive and 42c with a 120mm fan blowing at full speed in an OPEN CASE LYING DOWN, less than optimal for airflow. Worth the money, time and effort for this kind of improvement. Two thumbs up!

Looks like it. Tried finding a similar solution for Crossfire but hit a brick wall with this (you'll need to look through most the thread, answer regarding Arctic Coolings efforts at the bottom):

http://www.rage3d.com/board/showthread.php?t=33901641

Here's my problem; I'd like to use the Abit IX38-QuadGT and a couple of 3870's in Crossfire. The Accelero S1 is pretty much the best and quietest solution on the market so I'd really like to use it. Crossfire doesn't work with these cards so I need to look at 8800GT SLI and Accelero S1's - then I can't use an Intel chipset which I'd prefer and have to go for an Nvidia chipset.... maybe I'm just looking at the wrong boards but I haven't been blow away by the NV boards.

KuniD · Post by **KuniD** » Wed Dec 19, 2007 7:58 am

Hmm looks like I should eat my words, just found someone who has got Crossfire 3870 to work with Accelero S1's!

YL fans

BTW, grats on your 3870 El Jeffe. I'm glad I'm not the only one who chose the "inferior" product instead of the 8800GT! Long live competition.

In any case, I wanted to comment on your comments on temps. The last two cards I owned both made by ATI idled between 60-70C and load was 90C. Thats just how they are designed. GPUs can handle the heat. Over 100C, and you need to worry. But the 8800GT has been shown to run as high as 110C without crashing, as demonstrated by a passive 8800GT that tomshardware tested.

It's also true, most GPU heatsinks are not fully in contact with the things they are actually supposed to be cooling. Many times memory and VRM heatsinks are floating above the components they are supposed to cool! My 3870 heatsink had a thick layer of arctic silver lookalike goop on it, but it was thicker than it should have been (thermal compound is only there to fill in the cracks, not be 1/10" thick!!)

hm, friday and saturday i fiddle with my 3870. I am going to try and put on my ZM-GWB2 block on it. supposedly it doesnt fit but it looks like it does perfectly so we'll see. IF not, ill go S1 and side mounted fan.

Yes, 3870 is the competition. I wanted a low wattage idle with more technology in the item. Better 1080p video decoding/image quality, lower idle wattage with 55nm and powersaving, and HDMI audio/video out for when I want to add it to a new plasma display one day.

I know for a fact that the 3870 is easier to cool than a 8800gt, so why not? you need 2 slots to cool it anyways, so the single slot aspect of a 8800gt is not useful to us. It plays 1920x1200 games with af maxed and 2x aa on really well/smooth... shrugs good enough for high end gaming except for Crysis which is a dull game like farcry was and also poorly designed efficiency wise.

halcyon · Post by **halcyon** » Fri Dec 21, 2007 12:45 pm

Anybody got it working easily with 8800GTS (the 512MB G92 variant)?

What kind of temps are you getting?

ghettojiggalo · Post by **ghettojiggalo** » Fri Dec 21, 2007 10:34 pm

There is an S1 revision 2 out that gurantees fitment w/ 3850/3870 and 8800GT/8800GTS 512

http://www.arctic-cooling.com/vga2.php?idx=147

dammit.. i just bought 2 S1's that are now obsolete...=(

lemonparty · Post by **lemonparty** » Sat Dec 22, 2007 3:09 am

I can't see any difference between the old one and the new one, except the new one has 2 sets of mounting holes, so it can fit 8800GTS 512.

In theory it could also fit 8800GTS 320/640 or 8800GTX if more memory heatsinks and VRM cooling could be provided.

jwickers · Post by **jwickers** » Wed Dec 26, 2007 10:39 pm

BTW, for those in asia, Yeston is doing a 8800GT 512 with Accelero OTB for just 1900 rmb.

I've installed a passive S1 on my Galaxy 8800GT 512MB (stock speed) and it is miles ahead of the stock heatsink.

My setup:
Antec P182: 1 Tri-Cool on low as the back exhaust fan.
Intel q6600 (stock 2.4GHz) w/ Ninja Rev.B using the included Scythe fan (mobo controlled).
Galaxy 8800GT (G92, stock) passive w/ Accelero S1.

So there is only one case fan in the whole system and two fans total with the CPU fan.
Here are some test results. All temps in Celsius as reported by Speedfan (CPU) and Rivatuner+ATI tool (GPU).

Idle
CPU: 23-21-19-19
GPU: 43 mem: 38
Room temp: ~21

Load (prime + ATI tool)
CPU: 45-44-42-42
GPU: 57 mem: 49
Room temp: ~21

I think those are pretty good temps passive or otherwise, at least 15C less than the stock fan. I'll leave the S1 passive but i'll probably slap on a Scythe 120mm fan at 5V on it if i ever get to overclocking the GPU.

Misc. comments.
The ramsinks' tape is pretty bad. I scraped it off every ramsink and instead used some Arctic Alumina thermal epoxy. No chance of them falling off now.
As noted by others, not enough sinks are included to cover some of the circuits on the 8800GT, I dremeled out some heatsinks out of an old P3 heatsink. They work nicely.

I just got a BFG 8800GT

First time modding a graphics card

Could someone point me in the direction of a link as to how to remove the stock fan safely/intact?

Also are people getting better results w/ a 120mm yate loon or the turbo module (noise and temp drops)

Thanks!

The stock heatsink is really easy to remove, just remove all the screws and pull gently, it should come off easily, once it's off unplug the fan.

I am running a Turbo Module, at 9v it's quieter than a YL @ 6V and provide slightly better results.

AC TM @9v : Idle 39c \ Load 54c
D12SL-12 @ 6v : Idle 39c \ Load 56c

quick question

how many total slots are taken up when using the S1 with a 120mm fan strapped to it?

If it's a 25mm thick fan, 4 slots total. If you use a 15mm thick fan or the AC Turbo Module, it's 3.

Jerry_03 · Post by **Jerry_03** » Tue Jan 01, 2008 8:51 pm

Hey, im new to this forums and anyways ive read through this entire thread but im still not sure what cooler to get for my 8800GT.

most of the debates here are between the arctic cooling S1 and the thermalright HR-03. but im trying to decide between getting the Zalman VF900 or the Arctic Cooling S1 with the Turbo modular. both are HSF (im too nervous to try passive cooling as my case airflow wont be the best and noise isnt a real concern for me). so comparing these two HSF which one is the better cooling solution? right now im leaning toward the zalman

either one i get im still getting extra zalman VRAM heatsinks just to be safe.

im not real concerned about the price difference between the two. also im gonna buy some arctic silver adhesive cause i dont trust the thermal pads (on either cooler).

only thing that im concerned about is the extra slots the S1 w/ Turbo will take up. im willing to lose an pci-e but as i read in the above posts it may take up to 2 (as opposed to the zalman which would only take up 1 slot).

also i havent setup my system yet as im still waiting for the last components to ship. anyways ill be running my PNY 8800GT with the stock fan for at least a week until my aftermarket cooler arrives.

*edit*

another thing im a bit nervous about is can the S1 fit in my case? i have a Cool Master Centurion 5

lemonparty · Post by **lemonparty** » Wed Jan 02, 2008 4:17 am

If it's a minitower case and wide enough to fit a standard-sized DVD drive horizontally (perpendicularly to the motherboard), then it's pretty sure the S1 will fit.

Jerry_03 · Post by **Jerry_03** » Wed Jan 02, 2008 7:53 pm

okay good, the centurion 5 is a mid-size tower case btw. i went ahead and ordered the S1 with the turbo module. i was about to order the zalman vf900 until i saw this thread and it swayed my decision.

the S1 w/ turbo module will probably take up 2 more slots like the above posts said but thats okay as below my VGA slot is 2 pci-e slots and i wont be using them anyways (and if i ever do need a pci-e slot theres still one more above my vga slot).

also i have a question, is arctic silver 5 safe to use on the gpu? i read that the silver in AS5 might cause some problems if it drops down on your pcb. if i knew that i would of gotten mx2 as it doesnt have the silver :/

seraphyn · Post by **seraphyn** » Wed Jan 02, 2008 11:35 pm

Just don't overuse it and it'll be fine. I've used AS5 on my 8800GT + S1 and it worked like a charm.

AS5 isn't conductive despite the silver content, which is there for a reason. Also, if you're smearing it over PCB then you're doing something quite wrong.

Whoa didnt think it took up that many slots!

What do you guys rekon, the Accelero in Australia is $37 plus $12 for additional zalman ramsinks and also need to find a way to stick those accelero ramsinks on. OR HR03 GT for $61?

The HR03 GT takes up as much slots as the accelero right? Sucks having a cooler taking up so much space.
