Fix LSI SAS9207-8i Overheating In Desktop Computers
Вставка
- Опубліковано 10 січ 2019
- The LSi SAS cards are used by many people to expand the available sata ports in a normal desktop computer when running a home server. The only issue is these cards were designed to be in server chassis where there is a substantially higher airflow to keep everything cool.
In this video I will show you repasting the heatsink and adding a small 40mm fan and this combo has lowered the temperature of the card from 150'F down to around 85'F.
The issue with it running so hot at idle is many people have had problems with these cards in desktop situations where they are doing heavy disk access and the speed falls off since the card is overheating.
One item to remember is when adding the fan to the heatsink, you will block the PCIe slot below the card. In my case it was only a 1x PCIe slot that I was never going to use.

Did this yesterday with a 40 by 20mm fan. Took a few trips to the hardware store to get the screw lengths right. For those that opt to go with a 20mm thick fan, the screw is a M3, 30mm length. Long enough to get a rubber washer and a nut on the other end.
@@DS52116, metal. I used all metal and a rubber washer to prevent shorting a contact.
god bless you for this comment 🙏
@@fcktom glad it was helpful. Card and fan combo is still going strong.
@@fcktom +1!!!! just checked my card and its freaking hot, also my fans were on like 20% :S put them to 100 until the small fan arrives. Wish me luck that GF doesnt kill me till then
@@balazs_korcsog good luck 🫡
I just repurposed a larger heatsink by drilling two holes and mounting it with two screws and nuts on this model of card. It is a very cost effective way without buying expensive Noctua fans and the additional power and noise produced as a result.
Edit: Thumb up for the nylon screws very neat and safe way of mounting the fan and heatsink.
Just ordered. Thanks for the video!
I was actually going to watercool my 8805 just for kicks, even bought the block, but I got lazy in addition to it just not making good sense- so I slapped a fan on it. I knew I would need one after reading just how much airflow the manufacturer recommended. They were asking for values that would make my PC sounds like a vacuum cleaner without its own independent fan. It was super easy to mount with those extra long rubber mounting pull thingies.
Great idea. Going to do that.
I've been running an LSI SAS2008 9200-8i with TrueNAS in a desktop for a while and kept getting disc errors and a degraded pool because one or two discs would be "faulted" and removed. There was no data in that pool (array of 4 ZFS2 discs) so I didn't really bother out of a lack of time to really invest in fixing it. I replaced "faulted" discs a couple of times but the new ones always faulted. I finally set aside some time to tinker with it after trying replacing the SATA cables and changing the SATA port. Always the same results. Checked the logs: Always the same two discs... Touched the heatsink and burned my fingers. Watched this video. Shut down, pulled the card, removed the heatsink, cleaned and re-greased it & reassembled. Had a spare Noctura fan and attached it with two 3mm socket head cap screws down into the fins of the heatsink but with two rubber washers giving me ~3mm spacing between the fan and heatsink (which I think will give better air flow). Since reassembling everything, the system has been up longer without error than ever before. Thanks for being a catalyst!
PS: Cleaning aged heatsink compound does not seem possible with isopropyl alcohol but "Goof Off" worked great. I imagine acetone would work too -- only in a well-ventilated space!
I am facing the same issue third day, thanks, will do the same.
@@m1nusasusplus897 Mine has not shown these errors since I did this. Good luck!
Thanks a lot, great tip! I mount the fan by screwing into the heatsink. I was to afraid to unmount it, perhaps in the future...
I asked LSI and they don’t recommend removing the heatsink. So how did you attach the fan to the heatsink without removing it
@@nvidiashield495 with two small screws.
Nice job, i'm never that lucky
well done m8 , sure this will help a lot, but you add another problem; the slot next to it is unusable due to the fan, it might be just good enough to add only new paste and place a 80-120mm fan on the end of the card, that will help cooling the other cards too. Or; find a bigger heatsink with same thickness but twice the height or so.
its amazing how even a small low speed fan makes a big drop on temps.
It does that because the ic under the heat sink only consumes around 10 watts. A little airflow goes a long way with these, that's why they had no problem keeping cool without a fan in a server case as they are internal wind tunnels.
I know this is an old video, but I just recently changed my setup. This mod to the card I’m definitely doing with PTM7950. Should protect the card for years to come.
I bought an LSI SAS 9300-161 hba bus card that has a larger heat fin than this card you're working on so I'm going to find a way to finagle a 80mm Noctua (I have a box of them already) but this card doesn't have the brass retainers holding the heat fin on like yours. It has 3 screw/nut holding it on with little springs I'm assuming to evenly apply pressure. And I cant even get close to getting 2 holes to line up.
Rotate the cpu cooler 90°
I have a 7700k that runs 5.2GHz, I have my NH-D15 air cooler pushing air vertically from top to bottom due to RAM clearance issues. If you oriented yours to flow from bottom to top, it would pull a large amount of air around the card and cool it.
Hi! Bought mine and mine with epoxy. I can even turn it. How can dismount?
MAD what size screws did you use? I love this application. I am using a standard fan screwed to the case but would like the space for a hard drive so this solution would give me back the space. i am guessing 25mm since the fan is 10mm and the heatsink looks like another 10mm.
Q: How (and with what) did you clean the old thermal compound? I'm doing this to mine with either a Noctua NF-A4x20 PWM fan, or a much bigger heat sink. I have plenty of room for either.
Isopropyl Alcohol is usually the go-to for cleaning off thermal compound
IPA didn't work for me but "Goof Off" (my go-to for dissolving all adhesives and such) worked great.
Dumb question, but what's the operating temp for those Nylon screws? I'm worried they might melt if the temps are really that high...Is there really that much of a risk of shorting if I were to use metal screws and nuts
Nylon melts around 220C, so the chip will burst into flames before the screws melt.
Yesterday I saw you can have a plastic bracket made for this model card via 3D printing . The provide link and the comments have been removed by this UA-camr. Does anyone have this link ?
hey man, are you using jbod /IT on that card? which guide / firmware did you follwed/ flashed? +1❤
If you don't have one with a square heatsink you could get a pci slot fan mount.
Great video! A few years ago, I built my Dad a PC with a huge amount of storage - to satisfy his need to digitise his video collection. I used this LSI SAS9207-8i and four 16TB drives for around 30TB of usable space (RAID1). This card gets HOT. I can order the fan and the paste, but the nylon screws are hard to locate. Where do you get yours?
although quite an old video - as I'm looking up the nf-a4x10 fan on amazon there're two types: 3-pin flx and 4-pin pwm ...
anyway: is at least some mounting hardware included with the fan itself? otherwise I guess it's zipties then
I used my own hardware.
@@madelectronengineering I'm planing to buy one - and also the LSI card (that's what I search for and got your video) and also want to perform the fan mod you did
can to please tell me the inner-diameter or the threading-type/-size of your nylon-screws (and the required length would be nice, too) so I can order the required ones along the fan and the card (as my country is still in quite heavy lock down all the local hardware store still close so I have to order them online as well)
thanks in advance
I looked up the datasheet for the nf-a4 fans - but it does not specify the hole dimensions
for those just reading this post. 3pin fans use the 3rd wire to signal power adjustment by sending the speed of the rotation. Modern motherbords now use 4pin fans because the added 4th wire allows for PWM control. Noise is reduced most of the time while the 3pin fans the noise is steady and constant. It provides a longer lifespan because the fan rotates at the speed required. PWM provides automatic control thru the hardware
How big of a load is expected for the card to overheat like that? My four drives are mostly idle, should I consider repasting and adding a fan?
Remember these cards are designed to be in a server chassis with a ton of airflow going past them, this airflow is not present in a desktop case, which is why this mod is basically required.
LSI all run hot. 70-90c. Mine never slow down though. my 9286cv-8e runs the same at 65c as it does at 88c. No difference in speeds airflow is the key, I think the battery and chip maybe last longer cooler. I know the chips have a thermal shutdown, not sure about throttling, it could be corruption and resends and not throttling.
Do you run RAID on it, or do you use it for just extra sata ports.
Just extra sata ports.
@@madelectronengineering Did you have to flash the board to IT mode or it arrived flashed?
oh man oh man... do you know how I found this video? searching for "how to remove that gunk of the heatsink" isopropanol did not even put a dent in this. 40x40mm heatsink are quite common in IC cooling. It might just be better to buy a new heatsink. You can even get a full copper one for about 10-12£ you'll need to drill the holes tho.
80°C is still way too much! why is it so freakin hot??
I’m m from the future. How did this hold up?😊
gonna do this to my new-to-me lsi 9207 toniiiiiight, hope i can find some of those sexy nylon screws locally.
did you find the screws on amazon? what screws did you find good for space and length ?
@@shell11 actually i went with little metal screws, but i did use a little plastic washer to protect the surface-mount components near the screw holes. they were super cheap at an electronics store nearby. i'm sorry i can't give better advice than that :(
@@travnewmatic it's useful, thanks!
just water cool it!
What no LN2 pot?
Only downside is you blocking one of your pcie slots.
It's only blocking a 1x slot, not a big loss.
