8800GT 512 + Accelero S1 Cooler w/ Fans

[tuksonrider]

eVGA 8800 GT 512
Acrtic Cooling S1 heatsink
Azenx Bliztorm dual 70mm fan (exhause & fan)

Ambient ROOM Temperature 23C (73F)
Case: Antec 900 (4 Intake Fans / 1 exhaust fan)

Clocks & Temps (Idle/Load) Ati Tool:
700/1728/950 = 35C/44C
725/1760/1000 = 36C/45C

Package includes:
Accellero S1 Cooler w/ TIM applied
8 Ram heatsinks w/ double sided thermal tape (already applied)
2 types of vrm heatsinks for ATI cards
2 support clips
6 screws w/ washers


The S1 cooler is pretty damn big, but only took up one extra slot. It sits high above the card. For narrow cases or cases with an internal side cover fan, this may prove problamatic to install. I have an Antec 900 case, with a 120mm x 25mm fan. I had to move the fan from the inside to the OUTSIDE of the side cover just for it to fit.

Adding the fan module will take up another slot.

The S1 cooler is really, and I mean REALLY light weight. I didn't take an actual measurement, but it's light. It felt almost flimsy and low quality. I opted NOT to install the small support clips it comes with. I really didn't see the reason to.

I cleaned the surface of the heatsink of the stock TIM, and applied Ceramique. I did notice that the surface is really dull. I can literally see the vertical lines as if they cut the copper base with a bandsaw. I decided to lap it for about 5 minutes with 600/1500grit paper. The results were better. I only spent 5 minutes on it, just to reduce the grooves.

It attaches via 4 screws.

The 8 ramsinks were a PAIN to install due to the fact that the thermal tape doesn't stick to much of anything. Make sure the ram is COMPLETELY clean of any residue or even finger oil. If you're afriad they'll fall off, the S1 heatsink will catch them.

If you opt to use your own thermal adhesive, just a warning that it'll take some work to remove the tape that's been applied.

There are no heatsinks for the 8800GTs VRM.

I'm not using the S1 passively. I have a 70mm slot fan blowing directly on it, and another 70mm blower exhaust (azen Bliztorm).

The results were INCREDIBLY IMPRESSIVE!

Here's a screenie of my more real-life temps with my ambient room temperature of 23C (73F).

To show the OC scaling, the begining of the graph shows my card at what I play 24/7 (700/1728/950). Idle/Load = 35C/44C

Then I bump my card to 725/1760/1000. I let my temps settle, and run ATI Tool. Here mt temps at Idle/Load = 36C/45C

I'm not too familiar with ATI Tool, but I noticed when I scan for artifacts, my temp drops 1C. When I just run the 3D-View, the temp is peaked.

700/1728/950 = 35C/44C
725/1760/1000 = 36C/45C
No Errors/No Artifacts

Very cool. Looking forward to buying one of these. It'll be great with my new (full ATX) motherboard that should be coming in today. On my current micro ATX, i just don't have the space for it.

Thanks for sharing this , I'm also looking for an S1 for my 8800 GT. Your results are quite amazing , and because your temperature is so low, I would try a volt mod.

 

[angry hampster]

Also curious -- how does it run without the fans blowing around it?

 

[Tempered81]

yeah thats a cold running setup for the 8800gt when are you going to ovp and volt mod it!? try load temps at 860/2200/2000

The S1 is a killer hsf for the money. I slapped one on my 8800GT and zip-tied a couple 120mm fans on as well. With all case fans on quiet operation in a 75F room, I get load temps of ~51C playing Crysis.

Cool mod. The S1 might be another item going "Out Of Stock" soon at the eggy.

Man, you sure aren't kidding on that one!

I wasn't smart enough to use something like goo gone on the adhesive and my fingers still hurt from sandpapering the adhesive off the eight RAM heatsinks.

I cut up the spare long heat sink that came with the Accelero S1 and used it to get heat sinks onto the 2 groups of 4 small chips and the one medium chip (VRMs / MOSFETs?) that were contacting the stock heat sink. I had to work them a little because they were just tall enough to contact the heat pipe'd sink.

I haven't pushed further than the stock OC on the card, (I bought the BFG 8800GT OC from BB), but I did run the card through an hour of 3DMark06 and the peak temp was 50C. Not bad for a passive sink - I do have a case fan blowing in directly over the card in my Cooler Master 690 case, but it's blowing horizontal past the fins, and not through them.

Now I just need to get my E2160 up to 3Ghz, and enjoy my system!

 

[WhipperSnapper]

Do the Accelero 1 and 2 come with RAM heatsinks? Enough for all of the RAM chips and the medium chip? Is adhesive included for the RAM heatsinks?

Hmm I plan on possibly getting this fan when I get my new computer built with an 8800gt. I will also have the Antec 900 but I dont know if I want to move the inside fan to the outside to make space for this cooler..

 

[BlueAcolyte]

They come with ramsinks, yes.

 

[s44]

What about VRM cooling?

 

[Syntax Error]

This heat sink is looking better and better the more I look at it...what's the best way for a fan to be mounted reliably upon this heat sink anyways? Does the Accelero S1 have hooks or mounts that one can mount, say, a 120 mm fan on top with ease?

 

[bdubyah]

no it doesn't, but it shouldn't be hard to zip tie one though.
