| whaack: | diana_coman: EOD Report: Did 8h of saltmines, 1hr of Spanish, ~2 hr of 'writing time', but that was spent mostly researching reading #t logs + links. 45mins of setting up my comp was on my schedule, but I did not put anytime into that. (Also, my plan for this week needs to be updated to include which days I publish on) | [02:27] |
| diana_coman: | whaack: sounds ok. | [05:51] |
| whaack: | i need a better method or i'm going to be cleaning this heat sink all day. i was only able to obtain 90\% ethyl alcohol. i am putting the ethyl on the heatsink with a qtip and rubbing aggressively with coffee filters. i've made progress but every pass still seems to pick up some excess thermal paste. | [11:35] |
| whaack: | and with the cpu i'm going to need to be way more gentle imo. i haven't decided whether to clean it with it in or out of the motherboard. currently i plan to leave it in because i don't think i'm going to spill the alcohol and i'll leave it ample time to evaporate anyways | [11:36] |
| BingoBoingo: | whaack: If you have that much thermal paste on there, give it some passes rubbing with qtips | [11:38] |
| BingoBoingo: | But still finish with the coffee filters | [11:38] |
| whaack: | BingoBoingo: Yes i've been doing targeted qtip cleans as well for the nooks and crannies | [11:38] |
| BingoBoingo: | whaack: Just get the qtip soaked with solvent and hold it on the problem areas so the solvent bleeds into the paste. | [11:40] |
| whaack: | BingoBoingo: ah okay | [11:40] |
| BingoBoingo: | Let the solvent do the hard work, save your aggressive rubbing for once the bulk of the grease is gone. | [11:41] |
| BingoBoingo: | Maybe take some pictures of what you've encountered on the heatsink/CPU mating surfaces. | [11:42] |
| BingoBoingo: | If you've got thick paste you're fighting (which usually means far too much was applied), you can: 1. wet a microfiber rag with solvent 2. set the rag on a flat and clean surface unpainted/unvarnished surface 3. set the item to be cleaned paste side down on the rag | [11:46] |
| BingoBoingo: | whaack: If you do use the microfiber rag to prime the paste with solvent, do use a clean one you don't mind tossing. | [11:48] |
| whaack: | BingoBoingo: i'll post a pic of what i'm working with. it's not a matter of there being a thick crusty paste that's hard to remove, i just can't get it to a particularly shiny finish | [11:50] |
| BingoBoingo: | whaack: Still may be worth priming the past with a solvent rag, but the pics usually help | [11:52] |
| whaack: | ztkfg.com/wp-content/uploads/2019/12/DSC01052.JPG | [11:57] |
| BingoBoingo: | whaack: Yeah that's still rather dirty. Maybe not soak a rag dirty, but soak a coffer filter (or in a pinch, a paper towel) dirty. | [12:00] |
| whaack: | BingoBoingo: Alright i'll soak a coffee filter and place the heat sink on that for a while | [12:03] |
| BingoBoingo: | whaack: After 10 minutes or so wipe it dry with another filter. If you let if sit too long you'll lose solvent to the air. | [12:05] |
| whaack: | BingoBoingo: roger, timer set | [12:07] |
| whaack: | BingoBoingo: hm i think 10 mins may have been too long. it was almost completely dry when i lift it off | [12:19] |
| BingoBoingo: | whaack: Maybe something that holds more solvent than a coffee filter would help | [12:26] |
| BingoBoingo: | Just don't use toilet paper unless you want to remove a bunch of lint later. | [12:28] |
| whaack: | alright giving the rag a go | [12:33] |
| whaack: | BingoBoingo: gah not too much luck really. are those circles on the right side of the pic thermal paste rings, btW? | [12:58] |
| BingoBoingo: | whaack: It's hard to say from the picture. they could be joints between parts of the heatsink | [13:00] |
| whaack: | the real problem, from my limited knowledge, appears to be the residue inside the ridges | [13:00] |
| BingoBoingo: | whaack: What's between the ridges may be solder rather than thermal paste. | [13:04] |
| BingoBoingo: | Sure if rubbed hard enough, the soft metal in the solder can mark up what's being rubbed on it, but... it isn't going to dissolve in alcohol. | [13:05] |
| BingoBoingo: | What really matters is the flat surfaces that will be making contact are clean. | [13:06] |
| whaack: | BingoBoingo: k. looks like i'm getting some milage out of scrubbing much harder | [13:10] |
| BingoBoingo: | whaack: Maybe do a quick finger nail test. Does the stuff you are attacking behave like a solidified goo or when you poke it, is it more like a sort of pewter? | [13:11] |
| whaack: | BingoBoingo: i don't know what a pewter is, but if you mean some sort of dust/removable material - it's hard to tell since the residue in the ridges is hard to pick at | [13:27] |
| BingoBoingo: | whaack: Pewter's a sort of tin allow with properties similar to solder. If that residue just doesn't want to give... it could be the solder holding the thing together. | [13:38] |
| BingoBoingo: | whaack: The important thing is... does this stuff you are picking at interfere with the heatsink having a flat surface to mate with the CPU? | [13:39] |
| whaack: | BingoBoingo: no it doesn't, not on the edges, so you're right i don't think it will make a difference | [13:40] |
| whaack: | BingoBoingo: after much more scrubbing http://ztkfg.com/wp-content/uploads/2019/12/DSC01058.JPG | [13:42] |
| BingoBoingo: | whaack: That looks clean, give it a couple gentle wipes with the coffee filters and try to be more gentle with the CPU | [13:45] |
| whaack: | BingoBoingo: Alright. i think the pic makes it look a little extra clean because it is more of a birdseye view than the first pic | [13:47] |
| BingoBoingo: | whaack: Is anything at all coming off when you wipe gently with a solvent wetted coffee filter? | [13:49] |
| whaack: | BingoBoingo: not with the coffee filter but yes with the qtip | [13:50] |
