Throttlestop overclocking Desktop PCs

[Retrorockit]

Those tight fin server type heatsinks need a lot of pressure to get air to go through them. Noise is part of the deal I'm afraid. On my BTX builds I can funnel a 150x50mm 2xCPU workstation fan down to the heatsink . It's not too bad even at full speed.
It looks like you may have room in the front of the case for an AFC1512DG fan. DG168, MC527, NC466 are some Dell part# I think DG168 comes with a chrome grille sometimes. You could hollow out a 90mm fan for an adapter and duct down to that. They go for about $10.

I have been using arctic silver 5 but just ran out.

You can still buy it. However, Arctic MX-5 performs better. I did a series of tests last year that showed excellent performance.

[EOL] Arctic MX-5 is here!!Tests incoming! Completed. Now its MX-6 testing time!

Oh I'll pass on that. That's specifically for TFX. (I got the best results on my 3090 FE (most stable core temp deltas) applying it like that. SYY-157 still needs full coverage but is easier to get on. Anyone here use SYY-157 yet?

Just a suggestion.

I don't know where I'd put anymore. The whole front of the PC is a 3 fan module just like in a blade server. Ducts point to pcie cards and ducts to shrouds around memory with cutouts to dump airflow over the vrm area.

Haven't bought anything yet. Was looking around. But hey that's nice info. Can you tell me anything about the viscosity? If I'm going to lap this I'd want to go with something pretty thin to promote straight up metal to metal contact where it can. Arctic silver 5 is just a touch too thick and I usually don't see any areas where it has completely pushed out of the way. Always a super thin layer still left on those close area's.

 

[Retrorockit]

Never tried MX5 I guess it's newer than MX4 or the older Arctic Silver 5. Carbon nano material should crush down pretty thin and fill any tiny gap. Sounds pretty good to me.

The AFC1512DG just filled the front of the case by itself. and a 90mm fan next to it. It was cooling 2x 130W CPUs with no duct. It's in the lower right here.
https://flic.kr/p/6YDhA7 It replaces 2 of the 90mm fans.
Here's a picture of it in a T3500 with it housing MC527.

It is viscous and it's got a sticky quality. Takes some effort to spread, but the performance is up there with the best.

You should be fine. MX-5 does spread out under pressure.

That fan is impressive. Looking around and I can't find anything"good". A fan for my 5.25 bay would blow right into the cpu fan. A scroll fan would be ideal. There are some Chinese ones out there but I think I gather from the description that they exhaust not intake. And the reviews are pretty bad. Might have to do a diy sometime since I know I could buy everything to make it.

So I found this. Seller sent me an offer because I had it on my watch list. Really cheap but I have no idea how big anything is. I think I found the retention bracket on Amazon so I think I have that covered. Dynatron doesn't list anything like it. The pumps seem to be integrated into the fans so 2 fan connections and that's it. I do have some space top side of my case that I could cut to fit a radiator.
Btw I wasn't really looking for these. Just caught my attention with how low the offer was from the seller lol.

I would definitely buy that AIO. Especially if you have the narrow ILM bracket for it. It might free up the rest of your RAM slots.

The Delta AFC1512DG is a Dell only part.
I always have a few around and use them whenever I can.

San Ace 150 is the same size but more expensive and comes in a bunch of versions. faster, slower PWM, non PWM.

Actually all my ram slots are available. Doesn't look like it in the pics but I did try. Slots on both sides of the cooler work just fine.

And fyi since I can't help myself. Pissing with the kids PC now. Got a 4.8ghz run on user benchmark. Good thing the cpu test is so short lol. Temp goes wild fast. I'm going to try for 5ghz lol

 

[Retrorockit]

The info. on the RAM slots will be useful to others considering that cooler. Or maybe even something bigger that does cover those RAM slots. Is 120mm wide a possibility?
Could you get a link up to the Userbenchmark run. If you don't have a fast GPU they tend to get lost in the back pages. I wouldn't be surprised if you have the 1st OC T5810 there.

Found it. 91% CPU performance level, and 98th % ranking for that CPU.

[frankr2994]

Can't get past 4.8. I ran voltage up to 1.36 at which point it seemed that the voltage alone made it unstable. I couldn't get to the benchmark before it crashed. about 5 seconds after I applied the voltage it went down... below 1.36 it crashed at the beginning of the benchmark. So I guess 4.8 is max on that chip.

No you found the 4.7 run lol.

If you don't care about having 8 ram slots then yes a 120mm wide heatsink would work. note that you would not be able to use the ram cooling shroud either. I did have to cut the shrouds up a little to get them to fit around the heatsink. I only have them installed not to cool the memory but because they exit out to the side going to the vrm. Other than that there is no direct airflow going to the vrm. Before I realized that damn near every other dell system out there uses a square ilm I had bought a heatsink from I think a T7920. Pretty nice design and actually had a duct in it to push some of the airflow down low to go across the vrm. Can't make it work but I'd assume it works just as good as what mine does. Narrow ILM proved to be much more difficult than what I would have imagined.

 

[Retrorockit]

One of the German cooler companies I think Thermalright, but Maybe Arctic offers a narrow ILM kit for their coolers. TR Macho 120 was fun to put into the T3500 on page 9.
Did you try turning off HT? It doesn't look like it.

 

[frankr2994]

Thermalright makes coolers. I can't get them though. And yes Ht was on. I'll try it off but previously that only made a difference with heat/wattage and not max clock.

Yes, TR is my favorite but very hard to find. The threads match Dell hardware. The Macho 120 almost fits in a Dell workstation case. Like most ATX stuff it's designed to clear RAM slots anyway. But maybe not in the right direction for the airflow. Scythe Ninja cooler are huge and non directional airflow, but the cover will need to be spaced up to use one.

 

[frankr2994]

Ok so I might take the plunge on the aio. Means I have to cut pretty much the entire top of my case off to mount it. Which if I'm being honest I'd love to figure something out that doesn't involve just flat out hacking my PC lol. No pun intended. Anyways if I do that I'll take alot of airflow away from the vrm area. That's when I remember all the Dell dimension PCs I've scraped. Surprisingly I didnt keep any parts(I have lots of old useless parts) the green cpu cooler shrouds. They are for a 92mm fan just like I have mounted as an exhaust fan rear of my PC. One of those shrouds would attach to that fan and pretty much duct down right on top of my vrm. Then it's all on what direction everything is moving. Right now I have 3 intakes in the front and 1 rear exhaust. The aio rad on top would make sense to be exhaust but then I think I'd have to turn the rear fan into an intake. I could also flip my front fans and turn them into exhaust and my rad and vrm cooler be intakes. I can play with all of that but I'm still stuck on rad mounting. there is supposedly a aio designed for a 5810. If you ordered that as an option the rad mounted right over the cpu and the case cover was vented so it blew right out the side. I've never been able to find any of these parts. I'm pretty sure it was reserved for the few people that said F it and spent 18,000 on a Dell workstation. And by few I'm not actually sure there was any.

And the other thing I've noticed. I only started playing with it since I know the max clock I can hit on the 1650. The cache ratio. Default it's 12 min 30 max. I can set it to whatever I want but it only goes up to 30. From what I've read it doesn't make big gains but it's recommended to be up near clock speed. Anyone have any idea what locks that? I can adjust voltage for it to whatever and it sticks.

And for anyone with money. I was reading that the xeon w-3175x is a 28 core unlocked cpu. Uses a lga 3647 socket. It's stupid big physically. You can get over 5ghz on 28 cores but you need 1000 watt psu just for the cpu. Draws close to 800 watts lmfao. But for anyone willing I think for about 700-800 bucks you could put one of those systems together and have something faster than anything else for probably the next 4 or 5 years. I've only seen test using LN2 I'd be interested to see a "normal" liquid cooling solution to run it as a daily driver.

 

[Retrorockit]

Won't the AIO fit across the front of the case where the intake fans were? The old non BTX Dimensions with the pull through green ducts had the nice non PWM thermal control (self regulating) fans that can go any where as an exhaust and just need 12V. to run. That's where the Mangupta fan setup came from.

 

[frankr2994]

I hadn't considered putting the rad in place of the system fans in the front. However I think that aio takes 120mm fans. It would need to be 92mm to fit. Which puts me into custom loop stuff. I don't think I've seen an aio with a 92mm rad...but that does give me ideas. That would be very clean.

 

[Retrorockit]

I looked at the manual for that. It looks like they put the external drive bays on top of the cooling fans. It used to be the HDD bays there which could be discarded for SSDs.
It looks like they went to that setup from the T3600 on. Basically when they went with the plug in PSU system. Also no air intakes there any more. I suppose removing the drive cage would leave a hole.
But no easy way forward on that case setup.

 

[frankr2994]

I'll tear it all back down in a bit and do some measurements. I got some stuff lined up ahead of it though. I'm sick of not having a computer while playing so I'm going to get my T1700 sff up and running with windows instead of pfsense which was planned for it. I still need to run cat 6a through the house before I'm ready for that anyways. On the 5810 I've more or less gave up on the idea of using 3.5hdds in it. I may take the drive cage out of it. Spot welded in but whatever.

 

[Retrorockit]

Now that I understand that you may actually be stuck with 92mm fans there is an option. Delta made some GFB series 2 motor fans. GFB0912xxx should get you started. 103cfm but the noise is 61db due to the lower rpm range of 2 motor fans'

Or these which are probably 7000rpm fans.

[frankr2994]

I'm a little confused. I wasn't hunting for 92mm fans. The ones I have I think are adequate. I was only going over the scenerio of water cooling which would require a 92mm rad to make it clean. The vrm cooling with that dimension shroud I listed should work fine if I went that route. Or do you have some other idea I'm missing?

 

[Retrorockit]

I just always max out my fans. The cooler options on BTX are kind of limited so it's an old habit of mine.
You might like what these guys make. twice as thick as other coolers, and Copper construction. 440W rating for this size.

There seems to be a Gen2 version with 21fpi instead of 16fpi fin density. Probably better for dell fans if you can find one.

Just switched the GTX from suffix to prefix to find a different version.

 

[frankr2994]

Good find. Price isn't that bad either. I wonder if I could do something like that with a couple of nuctua fans and set the fan speed in bios to 100 percent so I could run 2 fans from system fan headers a water pump from another and run my vrm fan off the cpu header. That way it wouldn't give any warnings anyways. I was starting to lean towards not doing this but that find got me back in it lol.

 

[Retrorockit]

I bought a couple of their 80x160mm radiators to stack for 160mm to use my 150mm fan. But water doesn't go below ambient anyway. the BTX H2C Peltier water loop is BTX and at $20 pretty much takes the cake.

 

[frankr2994]

Well I just ordered an e5-1680v3. We'll have to see how she overclocks in about a week and a half. I am starting to get a bug up my ass on a dual cpu system. I think I might want a Dell t7810 with dual 2687w CPUs. Can't exactly overclock then but you can pull the micro code out of the bios to let them all core turbo.
