I get between 34 and 38 degrees C. The sink is not small enough at the moment to be able to use the PCIe slot beneath the card as it is 80Lx30Wx27H and I am looking at trying an 80x30x18 crosscut to see if I can achieve the same sort of results. The nice thing is I can now touch the heat sink and not get burnt. I will also be testing it with the smaller noctua 40mm fans to see if they are sufficient to cool it. If these work out I will be making them available for purchase, the current designs are only for standard desktop cases NOT for mATX or server equipment, I will be working on those next. If anyone is interested in the current ones let me know and I'll see what I can sort out at the moment my milling runs are only small so they are a bit pricey, the more of them I make in a run the cheaper it gets. Oh and you can reuse the existing mounting pins.<br />VaultDwellerhttps://www.blogger.com/profile/01392168890749740426noreply@blogger.comtag:blogger.com,1999:blog-128883176283300093.post-55406627624902760122018-02-22T18:20:06.560-08:002018-02-22T18:20:06.560-08:00Chris -

I had all kinds of strange trouble when I first put in my 9271-8i until I figured out my power supply was failing. New power supply and everything is great. It won't tolerate flakiness in power.<br /><br />DavidAnonymoushttps://www.blogger.com/profile/01590240430699631107noreply@blogger.comtag:blogger.com,1999:blog-128883176283300093.post-18277656000413525192017-08-05T10:06:32.774-07:002017-08-05T10:06:32.774-07:00Hi Vincent, thanks for you advice, I suspect it i...Hi Vincent, thanks for you advice, I suspect it is overheating although the room is at 18 deg C. I will visit the customer next week and open the computer which i did not do now. The computer was provided as an OEM for by the manufacturers their film scanning machine.<br />We have lost two drives and the computer crashes unexpectedly, this last time losing the config of the raid completely. I have seen battery backup modules for this raid. do you think it is worth having this <br /> thanks again for your help.vinhoscortemhttps://www.blogger.com/profile/12288922096666209672noreply@blogger.comtag:blogger.com,1999:blog-128883176283300093.post-17851451652561376942017-07-14T08:56:51.435-07:002017-07-14T08:56:51.435-07:00Hi Chris,
I wouldn't be able to know where you...Hi Chris,<br />I wouldn't be able to know where your problem comes from.<br />I'd advise looking at the HBA's log to see if there's anything relevant there. Check the iDrac's log too.<br />It could be several things: the backplane slot, the cables to/from the HBA.<br />One thing I know for sure is that the 9271-8i will most likely overheat in a tower server during the summer without additional cooling.<br />For my Dell PE T410 server, it resulted in the HBA shutting itself down and dropping off the PCI-E bus during a RAID rebuild.<br />At the very least you should make sure the fans are functionning properly and that the small heatsink on the 9271-8i gets enough airflow.<br />There's a temperature sensor on the 9271-8i, how hot is it? And check the drives' temperatures too. Some of them in the cage could<br />be running hotter than others, especially if this is a tower server.<br />The PERC cards usually have a larger heatsink and don't require that much airflow.<br />Good luck,<br />ElCoyote_https://www.blogger.com/profile/14677272516918697427noreply@blogger.comtag:blogger.com,1999:blog-128883176283300093.post-18609016088002975812017-07-14T01:00:57.414-07:002017-07-14T01:00:57.414-07:00I am reading this blog with interest as maybe you ...I am reading this blog with interest as maybe you experts can help us with a problem. We have a customer using a Dell server with MegaRAID® SAS 9271-8i 6Gb/s SAS and SATA RAID Controller Card.in a video strage application. For the third time we have had a disc failure in the same slot and occasional crashes of the computer with messages saying video storage is lower than it should be. The company who sold us the machine and computer has only changed the drive, but I am thinking that the raid controller board, the cables or maybe now overheating is the problem. Before I buy a new raid controller board SAS drive and cables, Have any of you have seen similar problems and could point to the probable cause.The system is in Portugal and quite hot in a snall room. I suppose there is a log of core temperature prior to failure of the disc. sorry I am not a computer engineer.<br />Thanks<br />Chris Price <br />info@cinesonics.pt vinhoscortemhttps://www.blogger.com/profile/12288922096666209672noreply@blogger.comtag:blogger.com,1999:blog-128883176283300093.post-61825748289270746452017-05-20T21:16:13.436-07:002017-05-20T21:16:13.436-07:00Vincent since you have - obviously a 9361-8i could...Vincent since you have - obviously a 9361-8i could you do me a really big huge favor and measure the size of the existing heatsync as I am looking at doing a custom made job for one of these and running long dissipation lines down to the PCI slot cover but as I don't have my card yet I can't start work on the idea.Anonymoushttps://www.blogger.com/profile/12010870813680047076noreply@blogger.comtag:blogger.com,1999:blog-128883176283300093.post-389433341299072862017-02-11T13:02:08.291-08:002017-02-11T13:02:08.291-08:00I was adding an LSI 9260-8i to my HP 420 Workstaio...I was adding an LSI 9260-8i to my HP 420 Workstaion server. The HP420 has a green-click used to hold the default-issue video card inplace. I used the clip to attach a fan over the video and LSI card as a cooler.
