From 9613ecf17c439032a51870d90b03836eeeb9de22 Mon Sep 17 00:00:00 2001 From: Raptor Engineering Development Team Date: Fri, 4 May 2018 04:16:54 -0500 Subject: Back off chassis fan proportional constant Ambient temperature swings should be slow enough, with a slow enough thermal response from the PCB, to make primary control via integrator viable. This slows down the fan responses and prevents audible "hunting" as the ambient sensor changes value more rapidly than the chassis fans actually need to react. --- .../fans/phosphor-fan-control-events-config-native/events.yaml | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'meta-openbmc-machines') diff --git a/meta-openbmc-machines/meta-openpower/meta-rcs/meta-talos/recipes-phosphor/fans/phosphor-fan-control-events-config-native/events.yaml b/meta-openbmc-machines/meta-openpower/meta-rcs/meta-talos/recipes-phosphor/fans/phosphor-fan-control-events-config-native/events.yaml index 22f02ae69..8aa842f6b 100644 --- a/meta-openbmc-machines/meta-openpower/meta-rcs/meta-talos/recipes-phosphor/fans/phosphor-fan-control-events-config-native/events.yaml +++ b/meta-openbmc-machines/meta-openpower/meta-rcs/meta-talos/recipes-phosphor/fans/phosphor-fan-control-events-config-native/events.yaml @@ -739,7 +739,7 @@ events: value: 1 type: int64_t kp: - value: 500 + value: 50 type: int64_t ki: value: 25 -- cgit v1.2.1
