Do you need to cool your RAM when the system is in sleep mode?

[char3327]

Hey y'all, 

 

So I am in a VERY confined space, and I was wondering... When you put your PC into sleep mode, do you still need to cool the ram? I know that when you put your pc into sleep mode it basically offloads all the current system info (apps open, programs running, etc.) onto the ram and no additional power is drawn. But does your ram still get hot?

 

Just a random question I had.

[adarw]

no, you never need to cool your ram, a heat sink is optimal but not nessary.

[Oshino Shinobu]

You don't need to cool the RAM even when it's actively in use, so no.

[CerealExperimentsLain]

When your computer is asleep it draws like less than 10 watts, meaning it can produce no more than 10 watts of power... So, no.

The entire PC is cool to the touch even.

Alright thanks!

As others have mentioned, the heat spreaders on RAM are mostly for looks anyway; even they are pretty much unnecessary. Active cooling for RAM would be a meme.

 

A meme that, of course, someone has actually tried to get people to buy, and of course "someone" here means Corsair: https://www.amazon.com/Corsair-Dominator-Platinum-Airflow-CMDAF2/dp/B077455184/

While this doesn't apply to op's question,  if you overclock the ram cooling can become necessary.  RAM above 50C becomes unstable,  it won't get damaged,  just unstable so cooling is necessary hence they have these "meme coolers"  : )

Meh just zip tie a stock CPU cooler on them and call it a gg. Or a 120mm fan or ...anything. If you overclock like that you have stuff like this laying around. I think the OC has to be pretty high for a cooler to become necesarry, right?

With 1.5v and up you want to move some air over your sticks. Maybe even 1.45v. For stock stuff that these guys are probably running it’s fine.

Yeh, I oc my ram @ 1.36v (1.35 crashes??) and its about 35-40c max, but if I'd push it a little more im sure temps go up. It was once at 46c, not sure why,  scared me a little lol.

Yeah, but wasn't these coolers "invented" for some really hot ddr3 stuff? i seem to remember reading something about that, not sure.

[Dedayog]

Yes, when my PC goes to sleep I put it in the refrigerator until I need it again.  Can't be too careful with RAM overheating.

DDR used to use 3v+. Those got warm.. DDR2 was 2v+ as well.. I don’t remember SDR having spreaders though. I only got into the hobby in the early 00s so my experience with SDR is limited.

Well what kinda ram was hip 11 years ago?

 

 

 

Note this is already the updated "silent" version.  : D

I used G.Skill PC8500, they scaled to 600fsb 1:1, my Dominators were PC8500 as well and topped out at 535 or so

 

Edit:

 

My Doms topped out at 545 weak.

Well also it helps not to watercool the CPU. My CPU cooler sucks in air across the dimms which is nice. I wouldn't be scared though, I think current (V's) kills RAM far more often than temps will.

I don't think I saw heatspreaders on RAM before DDR2 but I didn't see all the RAM so... Who knows.

Allgood man. My first set of DDR1 was some OCZ DDR400 with copper spreaders, sexy AF. 2-3-3-6 was their timings. Actually it was C2.5 but they would only run C2

Ah so it was ddr2 then that probably ran a bit hot...

 

 

Could also be used to comb your hair apparently! Such forward thinking!

Yeah I did some research on this, ddr4 ram is rated for insanely high temps (100c i think) but it does become "unstable" at around 50c... so better to avoid that. : o

Yup those are my Doms  I have them kicking around here somewhere. My G.Skills are still installed on my Rampage Formula lol..

Haha yeah. Hmm gonna see if I can find some kit like that and use as a comb actually. lol. Got heatspreaders on mine so I can't take their temp. Got a new kit in the mail, shame they don't have a temp sensor either...
