How difficult is it to replace the cooler on the 8800gt & replace it with a passive cooling option?
March 19, 2008 12:41:35 PM

as far as it goes. passive coolings at its best fails to cool down the 8800GT. comparing it to the stock cooler.

I beg to differ, you can get a good passive cooler from Thermalright that actually cools better than the stock cooler.

OP: please read the following review from anandtech on the Thermalright HR-03 cooler for the 8800GT. I had this cooler for my old x1900xtx and with a fan it literally cooler my GPU 20C better than stock. Passively it should be at the least comparable to the stock cooler.

Just make sure if you use this that you clean everything VERY well with q-tips and alcohol. Some people have issues getting the heatsink adhesive to stick. I had no issues what so ever but I thoroughly clean everything.

I was looking at the Arctic Cooling Accelero S1 Rev. 2 (on the ECS 8800gt). I'm debating between getting that card or getting another and adding the passive cooling. What I've read/seen is the stock coolers aren't that great, temps are high, but folks who have used the passive cooling have had much lower temps. My system is a Gateway Intel Q6600, 4GB Ram, and I measured inside the case, and it's got enough room to hold the 8800gt (I only have a 400w psu so I'll probably have to upgrade to 500w at least, so long as the amps are good).

My 8800gts isn't that loud except while gaming the fan kicks in a little. can't hear if much over explosions though. The stock 8800GT fan does get loud because its a hot little card. Look at that puny cooler...

Jay, any thoughts on the ECS 8800gt w/passive cooling?
March 21, 2008 1:48:55 AM

Well, I have personal experience with a passively cooled GT. I had it @ 700/2000, and had a 53c idle 70c load with the HR-03

I recently got a 92mm fan for it, which doesn't allow the load temperature to exceed 60c. I'm sure even if you wanted to go as far as volt modding the card, the HR03 could handle it.

I recommend getting the HR-03 + a super low RPM Scythe fan. I can't tell the difference with it on 100% or off.

What about the Arctic Cooling Accelero S1 Rev. 2
March 21, 2008 2:47:37 AM

I just put a Accelero S1 Rev.2 on my 3850. I didn't want to go passive so I straped on two 100mm Scythe Kaze-jyu fans (can't hear them at all - they're really quite).

My idle temps on the card are 28-30C and try as I may, I can't seem to break 35C under load (I've tried Ati tool artifact tests, oblivion, witcher, etc.). I've got the card clocked at 705/850 at the moment and I'm going to go higher and see what happens to the temps.

Anyway, I know the 8800GT runs alot hotter then the 3850, but given the results I've had so far, I'd say this is one really good cooler (and its half the cost of the HR-03).

I'm not sure about the ECS brands. I like to stick with the eVGA, XFX, etc brands that I know have good warranty support. It looks like the ECS just has an Arctic Cooler Accelero S1 cooler on it stock. It could be a good deal.

Just to be curious, what is the outcome you are looking for? Are you looking for the quietest system you can get? I stear away from passive cooling for gaming cards for the most part. How about a quiet fan setup? I hear the MSI 8800gt is pretty much the greatest cooler you can get stock and shouldn't be loud either. You probably won't be able to hear it over your PSU fan anways.

Oh yeah and Monst0r gave some first hand experience with the Thermalright HR-03, good call man.
March 21, 2008 12:53:03 PM

referring to anandtech article "Again, please note our test system had excellent ventilation and represents a best-case scenario, but even so this is quite impressive. Without a fan mounted on the HR-03 GT, RAM sink temperatures climbed to about 57C maximum"

i said what i said, referring to this http://enthusiast.hardocp.com/article.html?art=MTQyMywx... so if u are okay with high temp with passive cooling. i would say get the passive cooling.

otherwise, get the HR03 with a fan. of course, it wont be called passive. but it will be silent to some very true extend.

WoW, nice temps. I'm thinking about getting this HS but with a fan it takes up 3 slots. :(

In case your interested, here's a better apples to apples comparison - a review of the Accelero S1 rev.2 on the
8800GT both passive and with a fan:

http://www.hardforum.com/showthread.php?t=1261100

Seems to do better then the HR-03 GT passively and, with a fan, the same as the HR-03 GT with its fan on high.

Hope that helps,

Actually, I just read a review on the Accelero Xtreme 8800, that one looks a lot better. Too bad it's not for the GT though. Do you think they'll come out with one for the GT?

No I believe it would be liquid cooling or foam cups and liquid Nitro

@m2moore: Instead of spending $ to add a oem cooler to a 8800GT, why not buy a 8800GTS-512-G92? It is a bit faster, and has a very good stock cooler that sends the hot vga air out the back of the case instead of recirculating it.
March 22, 2008 2:54:50 PM

I don't think the 8800GTS will fit in my case... isn't it longer than the 8800gt? I have about 9.5 inches to slot a card in length wise, and the 8800gt is about 9 from what I've seen. My system is a Gateway GT5636E, so I'll need to upgrade the psu as well. I was looking at a passive cooling option, like the artic one, with the turbo fans for a quiet & cool performance.
How difficult is it, if I went the route of an EvGA or XFX as Jay suggests to take the stock fans off & replace w/ passive cooling? Or, am I going to void the warranty. The biggest concern, and granted I'm somewhat of a novice, with the regular cards is the amount of issues I've read up on about heat & noise... the xfx is reportedly set at a 100% and can't be lowered, while other ones, evga included, have all had reports of various issues. Just trying to make sure I get a good return on investment here. appreciate everyone's time here.

just buy a passive cooler but just slap a low rpm silent fan on it if noise is your priority.but make sure you have good airflow inside your case!!!always!!!

@m2moore: The 8800GTS-512-G92 is 9.0 inches long, exactly the same as the 8800GT and many other cards. You may be thinking of the 8800GTX which is 10.5 inches long, and will not fit some cases. I have had no noise issues with my EVGA-8800GTS-512. The fan spins up at boot time for about 5 seconds, but I never hear it after that.

Passive cooling will not work for any high card that will be good for games. A lesser card might work, but you would need a case with superb cooling.

It is not hard to replace a vga cooler. With EVGA, you will not void your warranty, just so long as you re-install the stock cooler if you ever need to return it for warranty. EVGA even sells a "akimbo" replacement cooler for the 8800GT. It is about $30, I think. It looks like the same cooler that is standard on the 8800GTS-512.

It is the 12v amperage capability that determines if the psu will suffice, not the wattage. The oem builders usually do not put in more capacity than is needed, but you may be lucky. There should be a sticker on your PSU that details the amps for each 12v rail, and perhaps the total it can deliver on all them. If it totals to 26, you should be ok. Can you find it?

30a. Your psu should be ok.
March 22, 2008 10:13:56 PM

yeah 30a will be ok to your case.but 35A just for safe measure.
March 23, 2008 1:32:37 AM

what's a good psu upgrade option ($50-$80 range would be nice on the wallet)
March 23, 2008 1:38:28 AM

the link i gave about you dont like it?its very good performance but at a very quiet operation.
March 23, 2008 2:07:32 AM

It looks pretty good iluvgillgill ... from some of the things i've read so far though the artic cooler has come out on top. I'm not sold either way, and have even looked at the gts models geofelt recommended. Trying to get something that will fit with my budget ... even reading up on some of the gts models more heat/noise issues. I really didn't think this would be that difficult when I began looking...
March 23, 2008 2:13:32 AM

well get a 8800gts and set the fan conseant at 45% and you will never hear a thing but load temp will nver go above 70Cor 65C on stock fan

if you're not going SLi, you can mount the HS backwards almost, so it wraps around to the opposite side of the card, and put a fan on there. then, you get all the slots below your PCIEx16 slot :) 

March 23, 2008 1:47:01 PM

Also, I can't SLI (not that I could buy 2 cards right now any ways) but my mobo doesn't support.
March 23, 2008 2:12:53 PM

Is either the 512-P3-N841-A3 or 512-P3-N841-AR good cards should I go the GTS route? Still not sold on whether to do that or go with a regular GT... trying to keep it down to appease the wife, while trying to get something that will last for a while. I do like the GT versions, from what I've seen... last two video cards have been ATI, so this would be a return to Nvidia for me, which from what I've read appears to be the better way to go any ways.

I'm sorry, HS? thnx. Also, not much room on the other side of the card. See link below for what case looks like on the inside:

http://support.gateway.com/s/Cases/3507131R/3507131Riv....

is that an ECS board by any chance? looks like my old ECS Nforce 570 SLI socket 775 :p 

anyway, it should fit, look how tight mine is :p 


March 23, 2008 10:39:45 PM

monst0r, what kind of psu do you have and what gt model?
March 23, 2008 10:49:27 PM

i have an ultra x-2 connect 550w.

uh, by gt model do you mean the brand? it was an MSI.


EDIT:

oops, just realized i didn't reply to this:

HS=heatsink

March 23, 2008 11:26:51 PM

oh duh, yeah, I guess I should have been able to guess heat sink. Which particular MSI one did you go with? I hear the stock cooling on the msi is a little bit better than some of the others.

nope, the same exact reference cooler on mine. you might find one with an upgraded cooler, i'm not sure.

i bought my 8800gt before the gts 512 came out..
i spent 260+50(HS)=310$ total on the card. for that money i could have just gotten the GTS with a nice stock cooler, but whats the fun of waiting :p 
March 24, 2008 5:12:37 AM

a 8800gts should be your choice if you are looking to spend some money and sell our old card.get a 8800gts 512mb remember
March 24, 2008 1:34:51 PM

No old card to sell... this is for my new system (can with a standard onboard video). Bought the system due to price for a quad core knowing I'd have to upgrade the video card.

Ive had two palit 8800GTX's since launch thats 16 months trouble free being pushed to the limit at 2048x1536 in games etc. However the early 8800 GTX's were all made in the same factory regardless of which manufacturer stuck their stickers on it, so the palit cards were identical to the xfx etc. No idea how current models are.
