I meant that the original chipset HSF is a bad joke - it was horribly noisy at 8,800 rpm (Asus A8N-SLI Deluxe). The NB-1 is a lot more heatsink, it's a bit heavier than a Zalman NB47J, and even a lower rpm fan does a fine job. But there are other problems: if I had a longer card than the 6600GT (or ...

Dysanovic, I used a fan controller to lower the rpm of the original chipset fan, not a software solution - although there may be such solutions, but they use to work with older mobos, not brand new ones. In the meantime I replaced the chipset HSF with a a Thermalright NB-1 and lowered the rpm of the...

Well, I thought about this kind of approach too, but didn't have the heart to slice in two the Winchester's stock heatsink (I use the XP-90 but bought the stock 3200). The solution doesn't look bad, although I don't think it's much better than a NB47J in terms of cooling power. But since it's usable...

Well, I just did the 3DMark overclocking tests: 266 'FSB' X9 multiplier, memory DDR444 1T, CPU 2.4 GHz at 1.475V, HT multiplier X3. The thermal probe reports just 1C more than at 200 'FSB' (36C instead of 35C), the same as the Asus probe. Subjectively, with finger-testing on the NB-1, maybe it's mor...

eander315, I knew about the patent on helicoidal pins for 3 years now. It is the first reason for not using the feature in a clone. The second reason is running passive: the helicoidal design is not that good when passive, since the heat transfer transfer through the pins is lesser compared to 'full...

I have the Thermalright NB-1 on my nForce4-SLI and the fan is running at ~4,700 rpm (still loud, I wish I had the low speed version of that fan). A thermal probe on the heatsink says 35C and by putting my finger on it I couldn't sense heat or cold, so it's at body temperature. I will do further fing...

The Delta 40x20 mm fan is about 25db, not 18, but it's still the quietest solution. I have a Thermaright NB-1 and the Delta 45x10 mm fan was a real screamer until I reduced the speed from ~7,000 to ~4,700, but it's still loud for me. I wish I could find a lower speed 45x10 mm fan. :-( The manufactur...

I have the mobo and CPU you plan to get. I have replaced the chipset with a Thermalright NB-1 and running the fan at ~4,700 rpm, from ~7,000, and it's still loud. The Zalman NB47J is silent, but you need to have some airflow over it, especially if you are overclocking. With my CPU I reached 2.4 GHz ...

Well, my prototype chipset cooler got built, and it sucks! :-( The design had a couple of faults, mainly that the fins are too tightly packed to allow decent airflow, but there were some manufacturing glitches too. I asked a friend of mine to take pictures of it and put them on a web site. When he w...

Interesting information, but I was hoping for something else, like Sorbothane grommets instead of the Antec ones. Sorbothane have a bushing / washer combo and a multi axis isolator - hard drive corner pad. I suppose that one should use the 70 durometer stuff, since the HDD vibration is in the 120 Hz...

niels 007, thank you for the answer. Bottom line seems to be that if the duct is properly designed / built, then the airflow loss is not major. I am going to put some original cooling ideas (designs with drawings) on a site, but right now I'm waiting for a couple of workers to finish my chipset heat...

I am unsure if 3DMark2005 can be run in a window, my unregistered 2003 can't. Temps drop very quickly after exiting a GPU intensive application. 80C is at the upper acceptable limit - people with Gigabyte 6600GT passive used to report these numbers. As long as you don't get artifacts, it's supposed ...

Well, I have pretty much the same setup (case, PSU, mobo, VM-101 on 6600GT, XP90, A64 3200). I have left the side vent open, I suppose you applied Acoustipack over all the case. My GPU idle temps are 42C and load (by Rivatuner) upto 68C when 3DMark-ing.

Speaking of complex fan adapters, how much airflow is lost?
I have a very complex adapter idea: from a 120 mm fan to two 120x20 mm targets, sucking air from two shrouded GPU heatsinks (SLI) to a case side vent.

May I suggest to install Rivatuner and record the temps while running 3DMark. You can expect those temps to be at least 10C higher than those reported in the display control panel. By the way, nice pictures... I have an Aerocool VM-101 on MSI 6600GT and I'm pretty sure about one thing: with passive ...

The top blowhole is something I want to avoid at all cost. But you gave me an idea (well, I'm not going to actually do it, I need my computer for programming...): move the PSU about 5-6 cm towards the front of the case, turn it 90 degrees to the right to exhaust air through the righ panel of the cas...

Well, after looking at several large blower fans (Papst, Sunon, Delta) it is now obvious that none is quiet or even quietable. And at the same rpm as an axial fan they only get 40% (at best) airflow. So my idea with this large blower fan (above the PSU) exhausting air is worthless

Thank you again for the answers. The standard 'slot blowers' are 70-80 mm and obviously loud in order to get good airflow. I am interested about that 120 mm blower by Sunon, I'll try to locate it. After looking at some 'slot blower' pictures I noticed that some are using a conventional (axial) fan a...

Thank you for the answers. The 'blowers' above aren't exactly what I want. An enlarged version of the AC Silencer - without the GPU heatsink - would be best. Or a large and quiet (quietable) exhaust blower, like one by Akasa (that one is of course not quiet, and it's smaller than what I have in mind...

Well, I made a crude ASCII drawing of the concept, please be gentle... ;-) ------------------------------------------------┐ <-``<-``<-``<-``<-{``I```I```I``}I ---------------------------`````````````┘ -------------------------┐``î``î``î``î``î`` <-``````````````I <-`````PSU``````I <-``````````````I ...

Damn, I couldn't find the right term for it! Maybe 'blower' would be better suited, it was used in the review of the Clever Power PSU... The AC Silencer fans are this kind too, they push air sideways through a duct - the GPU heatsink is in this duct - in my concept it would be a much larger fan and ...

Hi, For my case concept I need a quiet (or quietable) pusher fan that is 120 mm or more. It would be placed at the top of the case, exhausting warm air through a duct (~19 cm wide and ~3 cm height) that's over the PSU. It would be nice to have the pusher fan ducted (for the intake) to the CPU heatsi...

I have the Asus A8N-SLI Deluxe, 3200 Winnie, XP-90 and 6600GT with Aerocool VM-101, in SLK3000B with NeoPower480. For starters, you'll want to silence the Asus stock chipset cooler, and if you are not going to overclock, the Zalman NB47J should do. I have the Thermalright NB-1 and although I lowered...

c00z, would you mind saying what fan are you using on the NB-1? I am using it too on my nForce4-SLI, and the 45x10 mm Delta at full 7,000 rpm is very loud. I'm running it at ~4,500 rpm and it's still too loud for SPCR standards. Are there any 45x20 mm fans out there? Or a 45 -> 60 mm adapter? About ...

On nForce4 mobos currently shipping you can expect that a 4 memory modules configuration runs at DDR333 and maybe even single channel. This may change with new BIOSes and the new Atlhon64s with better memory controller. WindowsXP allows applications to use upto 2 GB of memory. WindowsXP 64-bit will ...

I'd really want to know where one can find those EAR grommets in the UK! Please help if you happen to know. I understand that they are built from softer rubber than the stock ones, but are they Sorbothane? I wish there would be some standardized / manufactured HDD suspension device that replaces the...

I have the MSI 6600GT PCI-E and the stock fan was a bit loud. I have installed the VM-101 on it, but now I have to increase a bit the rpm of my back fan in order to get the same temps. Probably the VF-700 would have been a better choice...

Ragnar, I'm glad your build is going well. I have replaced my chipset and GFX HSFs adn have posted some thoughts in the System Advice -> nForce4 chipset fan replacement thread.
Please post a picture of your setup there (I don't think I'll post of mine, I'm not so enthusiastic about it...).

I have replaced the chipset HSF on my Asus A8N-SLI Deluxe with a Thermalright NB-1 and the stock HSF on the MSI 6600GT with an Aerocool VM-101. The default NB-1 speed is at about 7,000 rpm, and it's as loud as the original one on the mobo, but I lowered it to about 4,500 rpm where it's acceptable. I...

Keoinn, The MSI Neo4 has a 24-pin connector, I think all nForce4 mobos have it. In principle when using a 20-to-24 pin adapter your voltages may drop a bit, and the same with a 24-to-20 pin adapter. My Neopower480 came with the latter adapter. IMO the Neo4 has the chipset HSF too close to the PCI-E ...
